Technologies Digital Insights

The future of healthcare is digital. In 2022 alone, the global patient portal market reached $2.9B, as the Grand View Research reports. By  2030, it’s projected to grow even higher—at a CAGR of 19.44%. This trend reflects how public and private healthcare organizations strive to digitize paper documentation and automate everyday business operations.

Indeed, the stakes in healthcare are high. Even minor errors can lead to incorrect diagnoses and worsen patients’ conditions. This is where patient portal software greatly minimizes errors, particularly those caused by human factors 

Below, read on how to create a patient portal. We’ll analyze the target audience’s needs, dive into the most successful examples of its implementation, and examine the nature of the target audience's requirements.

What is a patient portal system?

An online patient portal is a web or mobile solution (usually for Android and iOS platforms) that gives patients access to medical records, helps schedule appointments in a few clicks, and easily communicate with healthcare providers at any time. 

By automating the interaction between the parties via the patient portal, organizations can improve the quality of care while making their services more accessible and convenient for patients.

In particular, modern patient portal requirements are:

• Fast and secure access to their medical data and records with guaranteed privacy protection.
• High-quality medical services without the need to wait in long queues.
• A clear understanding of the treatment plan and progress.

Healthcare organizations instead aim to:

• Reduce their administrative costs – in particular, for maintaining paper documentation.
• Maximize personnel efficiency without the risk of burnout.
• Increase patient satisfaction through transparent interaction and remote patient monitoring.
• Comply with the healthcare regulations.
• Reach a new level of income by reducing expenses and attracting new patients.

That is why the patient portal system is the one-stop solution that, if implemented correctly, covers all the above-mentioned needs. This is typically achieved through the following features:

• Access to medical records (including medical history and test results).
• Appointment booking (with the option to select the date, time, and doctor).
• Online consultations (for example, via video calls and chats with doctors).
• Repeat prescription orders (automatic issuance of electronic prescriptions and reminders for refills).
• Online bill payment.
• Personal data management (including patient contact information).
• Push notifications (reminders for upcoming visits, tests, vaccinations, etc.).
• Educational materials.
• Feedback tools (surveys for patient satisfaction and forms for submitting complaints, etc.).

Types of patient portals: Which fits your healthcare needs?

Generally, there are two global types of patient portals: integrated and standalone. The former is presented as a component of electronic health records (EMR/EHR) and is fully tied to the infrastructure of a healthcare facility. Integrated portals ensure uninterrupted data exchange between doctors and patients but, in the case of ready-made solutions, are limited by the functionality offered by the specific healthcare provider.

Standalone portals, however, come in two forms: SaaS and on-premise. The former are hosted in the cloud and are available by subscription, which is especially convenient for healthcare providers within small organizations. Their advantage is quick deployment and configuration. At the same time, their customization options are often limited. 

As for the second category, these are software solutions installed on local servers of a specific healthcare organization. They provide comprehensive control over data but require significant infrastructure and support costs. They can also be difficult to scale and integrate with third-party solutions.

It is worth noting that every medical organization has its own regular processes and specific business tasks distributed among different departments. In particular:

• The reception desk keeps track of patient records.
• Laboratories collect, process, and store test results.
• The finance department is responsible for payments and insurance processes.
• Doctors and medical personnel work with medical records and appointments.

All the above processes can rarely be integrated into a single system, which makes it difficult to automate them using only one off-the-shelf patient portal. Moreover, medical institutions vary greatly in specialization (including clinics, dentistry, laboratories, hospitals, etc.), and ready-made products do not always meet their needs. 

If we add to this the need to comply with regional security standards for patient data, it becomes clear that out-of-the-box solutions may not be viable. This is the main reason why healthcare organizations are increasingly resorting to custom healthcare portal development.

Patient portal requirements: Key features and functionalities

Now, let's check the main functionalities and features that should be integrated into a patient portal.

User authentication and access management system

This portal component uses OAuth 2.0 and OpenID Connect for secure login. It protects users' credentials and enables multi-factor authentication. Usually, developers provide multi-level access with restrictions based on user roles (including patients, doctors, administrators, etc.). 

At the same time, when implementing role-based access, it is important to adhere to widely recognized patient data security policies, such as HIPAA and GDPR. Specifically, doctors and administrators should have full access to all patient data. In contrast, individual patients should only be able to view, edit, and delete their info.

Medical data storage

The storage is located on local or cloud servers using AES-256 and TLS 1.3 for data encryption. By the way, many cloud vendors have ready-made solutions for healthcare organizations that meet the standards of patient data privacy (including AWS HealthLake, Azure Healthcare, and others). It is also crucial to ensure that such storage is protected against data misuse and unauthorized access.

Integration with EHR systems

This integration is necessary for consolidating patient data. Thus, developers must adhere to FHIR and HL7 standards to ensure compatibility and data exchange. As for the integration itself, if we are not talking about legacy solutions, it is carried out through an API. 

Finally, to ensure that the patient portal system complies with the requirements of the National Coordinator for Health Information Technology (particularly, the ONC's Cures Act), it is essential that the platform could get full access to the patient, with all the ability to edit and delete.

Appointment schedules, doctors’ cards, and telemedicine tools

The first two components involve creating a catalog with therapists’ information and a scheduling system where patients can book visits. This can be achieved through RESTful API to synchronize with hospital calendars. Also, integrating with trusted video communication platforms like Zoom Healthcare can facilitate direct communication between patients and doctors.

Automation of bill calculations and online payments

Online payments are processed through integrations with payment gateways like Stripe or PayPal. In general, they must support PCI DSS standards. As for the automated billing system, this is essentially a regular calculator that “pulls up” data on the cost of services selected by the patient and sums them up (minus insurance and benefits, if any).

Integration with wearable devices

This is necessary so that doctors can monitor the condition of patients in real time. To do this, developers use APIs to collect data from devices (for example, from Apple HealthKit or Google Fit, as well as more specialized IoT equipment). At the same time, they must also implement a mechanism for obtaining prior patient consent to collect personal data.

Messaging 

It also makes sense to integrate a chat (with the ability to attach media files) for interaction with doctors, supporting end-to-end encryption (E2E) and using WebSockets protocols that provide real-time messaging.

User dashboards

The patient portal needs an interface for each user role. Basically, it should adapt the data and tools for doctors, admins, and patients. Among other things, it can also be enriched with advanced analytical tools. For example, Power BI or Tableau can be used to generate reports and visualize data (assessing attendance dynamics, treatment results, patient satisfaction, etc.).

How to develop a patient portal software: From concept to launch

When it comes to custom solutions, our telehealth website development services are provided in several subsequent stages. Let’s consider them in detail.

Ideation and requirements analysis

At this stage, our team consolidates the portal concept of custom healthcare portal development, according to your business goals, unique aspects of your internal business processes and IT infrastructure, the needs of the target audience, and an analysis of competitors’ strengths and weaknesses. Based on this blueprint, we create documentation indicating functional and non-functional requirements.

Architecture design

From now on, our patient portal development team has everything ready to define the project's technological stack (for the frontend, backend, and database) and choose a specific architectural approach. We also approve the necessary third-party Integrations (including EHR, payment gateways, telemedicine solutions, etc.). 

Finally, we select tools and protocols to ensure our portal has a proper security level, including data encryption, user authentication/authorization methods, diagrams of interaction between components, etc.

UI/UX design

This stage involves building interface prototypes and gradually transforming them into a full-fledged design after usability testing. At the same time, our patient portal app development experts always take into account the requirements for the accessibility of the user interface. Basically, they are most accurately outlined in the WCAG 2.1 and ADA guidelines.

Development

Now, we can start working on the frontend and backend of the patient portal. Once individual functional modules are ready, we conduct unit testing to prevent hard-to-fix bugs at later stages of the project. This stage also involves the implementation of security mechanisms and integration with third-party solutions.

Testing and quality control

When the code base is ready, our patient portal development experts conduct rigorous testing, including functional, load, security, usability, etc. This stage ensures that the solution meets the best specs and software quality standards in healthcare.

Deployment and launch

Before launching the portal, we prepare all the necessary infrastructure, build a CI/CD pipeline, and set up a monitoring system. If needed, we can train your staff on how to use the portal. After all the previous stages are checked—we usually start deployment.

Post-release support and updates

To better understand ​​​​its further optimization, our patient portal development experts regularly check the portal’s logs and metrics, collecting feedback. In addition, as post-release bugs are discovered, we fix them and, if necessary, implement new features.

Understanding the needs of your patients

A patient portal and medical website design should fully adapt to the target audience's problems. That is why it is essential to define them in advance. Based on our experience, we would like to highlight the following ones:

• Long wait time when making an appointment.
  Patients often encounter long wait times in phone and in-person queues. A patient portal can help. It lets users book online appointments 24/7 and choose a specialist. In addition, it sends SMS or push notifications to remind patients about upcoming visits.
• Lack of full access to medical data.
  Many patients are forced to visit clinics because healthcare organizations still document their test results manually. The patient portal gives access to electronic medical records, test results, and doctor recommendations, which can be easily downloaded or saved (for offline access).
• Lack of understanding of the treatment plans.
  Patients may find it difficult to track their treatments' progress, which may result in forgotten, delayed, or canceled visits and procedures. To prevent this, portals display the treatment plan and the current status of therapy. In addition, patients get notifications about upcoming procedures, calendars, and recommendations, which is very smart.
• Difficulties in paying for medical services.
  The need for patients to be physically present makes offline payments resource-intensive. Patient portals eliminate this headache with integrated payment systems, allowing users to view their payment history and current bills in just a few clicks.
• Insufficient communication with the attending physician.
  In-person appointments to explain test results and treatment plans can be time-consuming for both patients and healthcare providers. Patient portals streamline this process with online chat and video calling capabilities.‍
• Weak control over the treatment of chronic conditions.
  Patients with chronic conditions often lack convenient tools for regular monitoring. Portals can address this with real-time health data visualization, medication reminders, and appointment scheduling, as well as integrating with wearable devices for continuous data collection.‍
• Low involvement in the treatment process.
  Since some patients find it difficult to understand how their actions affect treatment results, the patient portal development team can also add interactive tools to the portal to track patients' treatment progress or provide educational materials.
  Gamification elements can enhance the effect.

‍

Patient portal development challenges and solutions

In this section, we will analyze the most typical challenges of patient portal software development and the most effective ways to overcome them.

• Ensuring compliance with regulations.
  Telemedicine hugely relies on strong data protection, first—to comply with laws like HIPAA and GDPR, and second—obviously, it is for patient trust. End-to-end encryption, role-based access control (RBAC), and multi-factor authentication are key practices, along with regular system audits and penetration testing to ensure security.
• Integration with existing solutions in the organization's IT infrastructure.
  Many healthcare providers still use older systems that don't easily connect with modern software. To solve this, developers can build 'middleware'—software that acts as a bridge—to automate data transfer between patient portals and other systems, ensuring everything works smoothly.
• Ensuring high performance and scalability.
  Many portals frequently freeze when user traffic exceeds the original design capacity. To solve this, developers can host the portal in a cloud environment that scales as users grow and use a microservice architecture to balance the workload across the portal's services. Additionally, they can optimize a database through indexing and caching.
• Ensuring intuitiveness. 
  ‍Since the target audience of patient portals is diverse (including the elderly, people with disabilities, and people with no technical literacy), there should be universal access to the full use of all portal functionality. To solve this, during the development of the patient portal software, the team should conduct user research and surveys to guide and optimize the software effectively. They should also adhere to the compliance of this software with the WCAG 2.1 guidelines. 

• Accessibility on mobile OSes.
  As patients increasingly manage their healthcare on digital devices, patient portals must offer a seamless mobile experience. Poor mobile optimization can lead to slow loading times and display issues. Developers can address this by building progressive web apps (PWAs) or cross-platform solutions, implementing offline access for key features, and optimizing content loading with techniques like lazy loading and data compression.

Patient portal software cost: What to expect

The cost of telemedicine app development depends on project complexity,  the team involved in the patient portal software development process, geographic location, development timeline, and the scope of features. Let's examine each of the points that influenced the cost in detail:

1. Project complexity

• Basic consultation apps with user registration, appointment scheduling, video calls, and messaging: $30K-$100K.
• Advanced telehealth platforms with multi-user portals, integrated EHR, and health analytics: $100K-$300K+.
• Telemedicine platforms with IoT/AI integration: $250K-$500K.

2. Team composition

A typical team for creating a basic patient portal usually includes:

• 2-3 developers: Where 1-2 are front-end developers, and 1 back-end developer.
• The project manager: Tracks the project goals and wins. 
• QA specialist: Tests the app to make sure it works correctly.

3. Development timeline

The time it takes for patient portal software development also affects costs. Most telemedicine apps take between 2 to 6 months to develop:

• Simple apps usually take about 2-3 months.
• More complex apps may take up to 6-12 months.

4. Geographic location

American tech experts can be expensive. For example, a front-end developer might earn over $100K annually, about $8K monthly. He might charge between $70K-$80K for a three-month project.

Hiring remote developers can save you money. For instance, Eastern European developers or other regions often charge between $2,500 and $3,500 monthly. You can easily hire a similar team for about $30K to $40K for the same project.

The future of patient portal development

In general, the future of patient portal software development is closely connected with the fast development of modern technologies, such as:

• Artificial intelligence and machine learning.
  These technologies will personalize the portal and related healthcare services. AI-powered chatbots, including ones with recognition of human voice commands, will assist with scheduling appointments and answering FAQs. In advance, machine learning can also analyze patient data and symptoms to provide preliminary diagnoses.‍

• Blockchain.
  The introduction of blockchain technologies in patient portals can be aimed at more secure storage of their medical records and ensuring access to them only to authorized users. In addition, with its help, each interaction with data (adding, editing, and deleting) will be recorded, increasing the system's transparency.

• Virtual and augmented reality.
  These technologies can form the basis of next-generation telemedicine solutions. In particular, in the future, patients will be able to interact with doctors at a distance without reducing the quality of service. AR interfaces will also help inform patients about upcoming treatment plans.
  ‍
• Internet of Things and integration with wearable devices.
  IoT solutions can provide end-to-end RPM in real-time (for example, portals will be able to collect and analyze data on the patient's pulse, blood pressure, oxygen level, and activity). Based on this data, doctors can receive instant notifications of critical changes regardless of patients' locations.
  ‍
• Big data and business intelligence.
  Examples of patient portals use big data to identify trends, such as tracking the rise in the incidence of a particular virus or assessing the effectiveness of treatments. Also, end-to-end medical data analysis ensures timely prediction of exacerbation of chronic diseases. Finally, doctors and administrators of healthcare institutions will be able to monitor departments' workloads and optimize appointment scheduling.
  ‍
• Biometric identification.
  Biometric mechanisms can give users access to the portal through fingerprint, face, or voice scanning, making the authorization process more secure and easier.

In recent years, mental health has taken center stage globally. Currently, approximately 792M people globally have mental issues and lack access to traditional therapy due to financial constraints or societal stigma. The best way to solve the issue — is to go digital. That is where mental health app development comes into play. It cuts costs and makes mental health available to everybody around the globe. 

As to the market, in 2024 alone, the app market saw expansion to approximately $7.38B. In a decade, forecasts promise growth up to nearly 10% annually, scorching $17.52B. 

If you are ready to build a new solution — now is the perfect time to start. Below, we will explain how to develop a mental health app, share standout mental health app ideas, and highlight key factors to keep in mind.

Why mental health apps are in demand

Even though people have faced mental disorders throughout the entire history, only in recent years solving these problems become normal and generally accepted. And it won’t stop. Let’s numbers speak louder — according to 2019 alone, the global capitalization for the global antidepressant market was estimated at $11.67B. By 2027, the market promises to grow to a record $18.29B. 

Of course, depression is not the only issue. According to the World Health Organization (WHO), there is a growing tendency for PTSD, anxiety, and OCD (due to economic instability, military conflicts, pandemics, as well as personal problems). 

Additionally, the fast-paced world daily brings panic attacks, triggers, and burnout (prevalent among doctors, teachers, and IT workers). Youngsters are prone to issues, too; among the most “popular” — are low self-esteem and social isolation.

Financial constraints and a lack of free time put hefty pressure on those who need a traditional approach to addressing mental problems. Then, an in-person visit to a psychologist or psychiatrist becomes a real luxury. But what if there is a more efficient, accessible alternative? That’s where developing your mental health app comes in.

Business and monetization models of mental health applications

For mental health app development, the following monetization models have proven to be the most profitable:

• Fee for the services of real psychologists.
  According to this model, the application acts as a platform, connecting users with professional psychologists, coaches, or therapists (similar to a marketplace with reviews, ratings, cost of services, and other attributes). In this case, the application earns the commission from each transaction (usually 15-30%).
• Subscription-based model.
  This model has a fixed fee for regular access to content and/or services for a certain period (month, year, etc.). If your app has diverse content and functions, offer multiple pricing models. This lets users pick a plan that suits their needs best.
• Freemium.
  These models give free access to basic functionality, with particular features to be paid. Usually, there are personalized recommendations, access to exclusive courses, advanced progress analytics, etc.
• One-time purchase.
  This model involves a one-time purchase of the application, after which the user has access to all its functionality.
• In-app purchases.
  Here, the basic functionality is available for free, but additional materials or services are paid (personalized plans, unique selections of tracks for meditation, etc.).
• Ad-supported model.
  In this case, app is free but includes built-in advertising (banners, videos, native advertising, etc.). At the same time, to improve the user experience, you can offer an option to turn off ads for an extra fee.
• B2B model.
  This model translates into you selling licenses to companies with internal programs to support employee mental health.
• Selling merch.
  This model focused on branded wellness merchandise promotion via scented candles, self-improvement guides, and mindfulness notebooks.

Top mental health apps on the market

Now, let's explore the most popular mental health apps. Perhaps they'll give you extra inspiration for your mental health app development project.

Headspace

Endorsed by the editors of the New York Times and 2.8 million users globally, Headspace is a product of the mental health company of the same name. Its core functionality includes meditations dedicated to improving sleep quality, relaxation, and cultivating mindfulness. They also offer courses on meditation, managing borderline emotional states, and more. Moreover, the platform has scientifically proven results in stress reduction and a user-friendly interface.

Calm

The Calm app is loved for high-quality content and a simple and intuitive interface. by 4.5 million (2023). And it is rightfully so. This app spins everything, from meditation sessions and effective breathing exercises to audio programs that are good for falling asleep faster. As for monetization, there is a free version with limited access.  Full access to functionals is only available with a paid subscription.

BetterHelp

BetterHelp has over 2 million users and connects with licensed therapists via text, phone, and video. Patients must pay a fee to continue their subscription and can also volunteer to donate to others. This app goes far beyond mood issues. It covers complex disorders and symptoms, such as clinical depression and PTSD.

Talkspace

Talkspace provides online therapy with licensed therapists through a tiered subscription model (with health insurance coverage). Moreover, this app is ideal for managing medication treatment and has many formats for direct communication with psychotherapists (including cases of emergencies).

Moodfit

Founded in 2018, Moodfit has become the top mood assistant for more than a million people worldwide. It has personalization options, customized mood data analysis through visualization tools, and mood-improving recommendations. In addition, the app has cognitive-behavioral therapy exercises as a handy and entertaining way to deal with mental issues. 

Woebot

Woebot is a free AI-driven bot founded by Dr. Alison in 2017.  It is based on text format and has cognitive behavioral therapy methods. Initially, this software was intended for youngsters in college and graduate school, but today, people of all ages use it.

Sanvello

Sanvello, created by Dale Beermann and Chris Goettel, provides evidence-based CBT techniques and tools to support mental well-being. Since 2015, the app has offered free features and premium content through subscription or insurance.

Key components of a mental health app

Let's determine what mental health app features should be included by default.

Registration/authentication/authorization system 

The main functionality of this system includes two types of registration: full-fledged, with the user’s email, and fast, through social networks (this is implemented through the OAuth 2.0 protocol, which is suitable for integration with Google, Apple, and Facebook). 

For better protection of user data, use two-factor authentication and store hashed passwords. This can be done, for example, using bcrypt. Additionally, allow password recovery via email or SMS and register log-in/logout events for a data security audit.

User profile

Include the functionality for adding, saving, and changing personal information (name, age, mental health goals), maintaining the user’s activity history (exercise completed, courses, sessions with psychologists, etc.), and privacy settings (public/anonymous profile). Typically, profile data is stored in a relational database (PostgreSQL/MySQL); it is also necessary to set a clear separation between public and private user data.

Home screen and navigation

The home screen should feature a clickable menu, allowing users to update content based on their settings. You can also add push notifications (for example, using Firebase Cloud Messaging). As for the menu, place meditations, psychological tests, stretching, and yoga exercises in text, video, and/or audio format. You can also include real-time communication with specialists via text, voice, and video chats.

Use cloud platforms such as AWS S3 to ensure scalable content storage. If your application is media-rich — add media streaming via HLS. 

Finally, localize content for users from different regions if you plan to maximize your target audience. 

In-app payment system

If you plan to monetize your app through subscription payments or in-app purchases, integrate App Store and Google Play to process payments via the In-App Purchase API. You can deploy the web version via Stripe. Once everything is ready, provide access control based on the paid features.

Analytics and recommendations

Place functionality for tracking user progress and boosting their motivation (e.g., mood changes) and recommendations based on analytics. The latter makes sense to implement using machine learning models (e.g., based on TensorFlow).

What to consider before creating a mental health app?

The basic functionality of a mental health app goes far beyond making it popular and profitable. Therefore, to maximize your chances of success, consider the following factors before creating a mental health app.

Competitive environment

Usually, it involves the user interface, content accessibility, and the quality of the exercises/recommendations. Notably, the Calm application (sleep stories) and BetterHelp (online chat with therapists) are prime examples of such. 

Analysis of bad ratings — matters too. In particular, users usually complain about the high subscription costs, lack of personalization, navigation problems, and negative experiences with customer support service. You can use it to make a competitive feature. 

Target audience

Your target audience — above all. This can be young people (18-35 years old) who need an effective solution for stress management and improving sleep quality. Or the elderly might be searching for a more convenient professional in-home/palliative care format. Finally, it could be corporate clients who want to implement programs for the mental support of their employees. 

Ultimately, user needs may vary. Based on the insights, determine the preferred content format (e.g., meditation, CBT, DBT, video sessions) and presentation style.

Regulatory requirements and user data privacy

The most common and comprehensive regulations are GDPR and HIPAA regulations, which govern the processing of personal data and medical information. To comply with them under the mental health app development process, you must implement data encryption (via SSL/TLS) and ensure transparent privacy policies.

Marketing strategy

To attract a broad user base, create a unique selling proposition. This can be achieved through AI diagnostics, integration with wearable devices via IoT, or simply offering a lower price than competitors. Next, point out the comprehensive marketing strategy. Select the right promotion channels: social media, partnerships with therapists, or advertising through user reviews. is essential for developing a comprehensive marketing strategy. Additionally, to retain users — regularly update content. 

Testing and feedback

It’s better to subject an app with a diverse target audience to beta testing. To do so, find the first users who could be your potential consumers, gather feedback, and optimize the app based on their input.

Financial costs and ROI

Finally, estimate the project budget. It should include development, marketing, updates, customer support, and infrastructure maintenance. Given the costs, you must also estimate how long it will take till your project is profitable. It might be useful for future investors.

What are the main phases of mental health app development?

Now that you have so many insights at hand, you can start the mental health app development process. Let's find out how this happens in practice.

Ideation 

First, define the problem. It is the mental health issues that trouble your audience and their goals. Obviously, your app should cover it. The solution might vary. It could reduce stress, help with sleep, or heal depression. Moreover, in the very first stage — conduct a competitive analysis. This will help identify niche leaders, find the target audience, and formulate a USP.

Planning 

At this stage of the mental health app development process, you will already have enough information to determine the main functionality of your teletherapy application. Select a technology stack (or at least decide whether it will be a native or cross-platform solution), and clarify the business model. Based on this, you can calculate an approximate project budget.

Design 

From now on, your mental health app developers can start creating prototypes and gradually turn them into a full-fledged design. Note that to develop mental health apps, you must use WCAG 2.0 guidelines, which ensure all users can access the app's functionality. Once the mental health app design is complete, test usability with real users to refine the navigation.

Development 

The mental health app development process is divided into frontend and backend. The first includes the implementation of the user part of the software, and the second – everything that happens on the server side. As individual modules are ready, your mental health app developers will need to perform unit and integration testing to prevent difficult-to-fix bugs in the future.

Testing 

Once the entire codebase is ready, QA specialists and testers will create test cases to ensure each function works correctly and the app performs well under high user load. This testing also ensures that all user actions within the app are secure and protect their privacy.

Release

Now that testing is complete, and all detected bugs are fixed, you can publish the application in the App Store and/or Google Play (your development team will first need to check whether it meets all platform requirements). After publishing, you can launch an advertising campaign to attract the first users, as well as set up tracking tools like Google Analytics and Amplitude to analyze user behavior.

Post-release support

At this mental health app development stage, you must check your application's speed and stability regularly. You will also need to update/expand its functionality once in a while and optimize what already exists based on feedback from real users. An equally important point is ensuring compatibility with newer versions of iOS/Android.

Challenges in mental health app development

Various challenges can arise during the mental health app development process. Let’s analyze them:

• Compliance with regulations.
  Mental health apps often handle and maintain personal information, including medical data, which imposes obligations on you as a developer to implement GDPR, CCPA, or HIPAA compliance.
• Balance between personalization and privacy. 

While personalization — is a key feature of these apps, it sometimes conflicts with privacy requirements. To address this, implement advanced mechanisms for anonymizing user data, which will reduce the need to send sensitive information to the server.

• Evidence base.
  The content provided by your app must be scientifically sound and effective for users. To do this, you should either accompany all your treatment plans with individual recommendations from real therapists or initially use approaches with proven effectiveness.
• User retention.
  Many users abandon apps after a few days of use, so your app may need additional retention mechanics (such as gamification and adaptive push notifications) that won’t make users feel guilty or overwhelmed.
• Monetization efficiency.
  Most users search for free or cheap health-related apps. At this point, you need to figure out the balance between user accessibility and the financial sustainability of your software.

How much do developers charge to build a mental health application?

The budget for developing a mental health app development depends on its complexity. So, we can't give exact numbers without first discussing your idea with your development team. But the approximate price ranges from:

• $140K for a teletherapy app.  
• $70K for a simple mood-tracking app with self-monitoring features.

Back-end features, like a database and admin panel, are often overlooked in cost estimates. Developers typically include these in the overall pricing for mental health applications.

Mental health app design: Best practices

Now, let's analyze several mental health apps (some of which have already been presented to you above) whose design has pleasantly surprised us. Maybe they will help you think better through your mental health app development process. 

Headspace

This app is praised for its simple and minimalistic interface, with bright illustrations and smooth animations that literally "nudge" users to meditate with its help. It is also adapted for beginners and is generally perceived as intuitive. This approach to design minimizes anxiety in users and motivates them to meditate regularly.

Calm

The aesthetics of the Calm app lie primarily in the author's images of nature, a soft color scheme, and smooth animations. Together, they create an atmosphere of relaxation  - that’s what you need to reduce stress. The app also stands out from its competitors with its "sleep stories" that help people with high anxiety fall asleep faster. 

Reflectly

Reflectly's unique design uses artificial intelligence to offer a personalized experience. A clear, user-friendly interface, dynamic prompts, and mood analytics complement this. Together, these features make the app an ideal choice for audiences of all ages.

Daylio

Daylio's intuitive interface is accompanied by simple icons for tracking the user’s mood and activity. Moreover, all these application elements are easy.

Mental health app ideas to succeed in 2025

In this section, let’s look through the most viral mental health app development ideas so you can pinpoint your project to success:

• Integration of AI.
  AI assistants can help analyze moods and behavior patterns, give personalized recommendations on how to improve well-being, and remind them of any regular upcoming activities, like a daily mood rate system.
• Social interaction.
  This can be implemented via in-app groups of users with similar mental problems where they could share their healing experiences and receive mutual support.
• Integration with wearable devices.
  Through the IoT, you can analyze heart rate, assess stress levels, determine sleep quality, and create a common mental health map.
• AR and VR tools integration.
  It might be useful for relaxation (to enhance the immersion effect).
• "Instant help".
  Through the screen for quick access to ready-made materials and an online chat with a psychotherapist.
• Content specially adapted for children and adolescents.
  For example, these could be games for managing emotions or recommendations for teenagers on dealing with anxiety and stress;
• B2B solutions for companies.
  in particular, these could be psychotherapeutic assistance to prevent burnout.

Highlights of our experience in delivering healthcare solutions

Finally, we'd like to share our experience developing a mental health app. A client approached us to expand their services to the web, specifically to support small businesses recovering from the recession caused by the coronavirus pandemic. The objective was to create a platform to attract a target audience seeking health-related products and services.

For this project, we assembled a team of ten specialists. We chose Ionic and Vue.js for the frontend tech stack, with Laravel for the backend. The result was an online platform featuring a simplified login process, the ability to schedule and reschedule meetings between clients and trainers, an intuitive search for events and classes, role-based access, and an integrated payment system for online payments (covering group and individual courses, as well as event participation). We also implemented live session connections via Google Meet and Zoom. The solution was complemented by a clean, minimalist design with a calming color scheme, ensuring a pleasant and user-friendly experience.

In recent years, healthcare IT outsourcing has become a top solution for healthcare organizations in the United States, and even in 2024, it still holds positions. Actually, the U.S. healthcare IT services market was worth $11.44 billion in 2023 and is expected to grow to $52.59 billion by 2033. This occurrence continues to grow because of the huge demand for solutions like Electronic Health Records (EHRs), telemedicine, healthcare data analytics, cloud computing solutions, AI-driven diagnostic tools, etc. It is essential for healthcare organizations of different sizes and types, like clinics, labs, fresh startups, and medtech companies that develop hardware. 

Outsourcing helps organizations to allocate their resources more efficiently and enables them to invest in other critical areas such as patient care and service expansion. It also helps them avoid any issues connected with strict regulations, because outsourcing companies have expertise in building secure systems for data protection and privacy, so they stay updated with upcoming changes, and implement necessary updates to maintain compliance. 

Generally, healthcare organizations in the USA often rely on IT outsourcing for solutions such as:

• secure hospital management systems;
• telemedicine platforms;
• medical billing software;
• data analytics tools;
• remote patient monitoring;
• mHealth apps;
• system integrations;
• secure cloud storage for sensitive data.

As the healthcare industry evolves, the necessity for improvement and expansion of IT services grows. This is where web and mobile app development, quality assurance testing, software development, and UI/UX design help meet this demand and improve patient care. 

Moreover, AI is being integrated into healthcare technologies, providing advanced predictive analytics and automation. This means providers can streamline administrative tasks and improve patient outcomes. 

It is more effective to combine the integration of technology and design simultaneously, so when a company handles both development and UI/UX design, it ensures smooth collaboration between teams, helps to detect early issues and reduce the risk of rework or delays. This approach keeps the project on track, improves cost efficiency by minimizing operational expenses, and provides flexibility for adjustments based on client needs. Plus, it helps to match the final product with the original design vision.

‍

If you have an idea for implementing a digital solution, but its business model is not yet clear, you may need a lot of resources to find the right one. But how can you test the effectiveness of this idea in practice when each of the potential target audience’s representatives may perceive it differently? The answer is simple: you should consider minimum viable product or MVP development for startups. Below, we will explain its peculiarity and analyze the advantages of this approach.

What Is an MVP for a Startup?

An MVP for startups is a software solution with a basic set of functions and a simplified visual that clearly demonstrates its unique selling proposition (USP) and does not have any additional features (that is, if you remove something from its functionality, it will lose this USP).

The Importance of MVP Development for Startups

The main purpose of MVP development for startup is simple: since early-stage startups do not have clear, verified business models, it is important to make sure that they will be accepted by their target audiences. Otherwise, their owners risk losing a lot of financial and time resources on something that “does not work” for the end consumers. So, to avoid this, it is better to implement such projects gradually, optimizing and expanding them, taking into account feedback obtained from real users.

MVP Development Process

Here are the main stages of the MVP development startups process:

• Defining the problem or goal of the target audience that you are going to help them solve/achieve with your product;
• Conducting market demand analysis, which consists of a detailed study of the target audience, market trends, similar software solutions, etc.;
• Rapid prototyping of the future solution and defining its key features that form the USP;
• Agile development of an MVP;
• Collecting feedback from real users;
• Continuous product iteration after the MVP launch aimed at tailoring the product to the needs of its target audience.

Top 9 Benefits of Building an MVP for Startups

In this paragraph, we would like to introduce MVP benefits that are valuable for each startup owner.

Cost Efficiency

Creating a minimum valuable solution is, first of all, much cheaper than in the case of a full-fledged one. This means that the initial budget for your project will be moderate, and you will not have to sacrifice anything important – for example, the budget for marketing, the salaries of your full-time specialists, and so on.

Faster Time to Market

No matter how unique your idea is, there is always a risk that someone will follow your example before you. In turn, the implementation of the MVP will allow you to reduce the time-to-market and, thus, gain an additional competitive advantage.

Market Validation

A quick launch of the MVP will help you validate it in real market conditions as fast as possible. In the future, you will be able to optimize it based on real feedback from its users and then improve it with each iteration and make it more and more valuable to them.

Risk Mitigation

Getting a working solution up and running quickly will help you identify its hidden issues early on, all thanks to the fact that it will be accessible to users from all over the world. In fact, no other type of testing, no matter how many resources are involved, can provide the same thoroughness in identifying errors and inconsistencies.

Investor Attraction

By launching a “raw” but functioning product to market early, it will be available to potential investors, too. Agree that this approach to demonstrating your idea looks much more viable and capable of achieving your goals than presenting a business plan only.

Customer-Centric Development

Generally speaking, creating a minimum viable solution is one of the key startup success factors since its entire development cycle is tailored to “please” its target audience. Indeed, since user feedback has to be taken into account long before the solution is released (first, it is tested by the project team and then – by representatives of focus groups), it turns out to be truly focused on the needs of the end users.

Enhanced Learning

MVP in startups helps to conduct an end-to-end assessment of market needs and make decisions based on the data obtained. This way, you can use the obtained insights in the further evolution of your product, turning it into a full-fledged software solution step by step.

Flexibility and Scalability

MVP development for tech startup involves creating an initially scalable, flexible foundation that is easy to modify and to which you can quickly add new/remove unnecessary functionality without much risk (primarily, associated with the appearance of hard-to-fix bugs).

Building a User Base

Finally, when you launch a full-fledged solution, it will already have some audience interested in using it. Thus, you will be able to reduce your budget for early adopter engagement and, in particular, the time and money needed to research and create a portrait of a potential client.

Conclusion

Now, knowing all the advantages and goals of startup MVP development, you can understand whether this option is right for you. In particular, if you are inclined in its favor, you can contact us, a service provider with many years of experience creating MVP solutions for startups in different industries. We will accompany you throughout the entire lifecycle of your project – from the ideation stage to the release and support of its full-fledged version.

Most likely you have used these digital tools at least once – Google Docs, Dropbox, and Azure. They are based on the SaaS model. Apart from this widespread one, there are other variations of cloud application services, such as PaaS and IaaS. You will find out about their differences in this article, so keep on reading it. ‍

IaaS, PaaS, and SaaS: Pillars of Cloud Services at a Glance

The highlighted models – IaaS, PaaS, and SaaS – are aimed at delivering digital tools and services to end users through the cloud on the subscription basis.

According to each aforementioned cloud model, end users don't have to pay for these services and tools one time – instead, as they are owned and supported by a specific vendor, the users are provided with entry credentials as they pay for a subscription. Only a steady web connection is needed to start using such a cloud application. At the same time, entire maintenance efforts in terms of cloud services remain on the provider's side. Even more, users are allowed to optimize their own facilities by offloading apps. Thus, they get more space while specific info is stored remotely on a secured server. 

Let's take a deep look at each of these variations:

• IaaS – stands for Infrastructure as a Service and implies access to demand compute, storage, and networking resources, according to the pay-as-you-go pricing model. In this case, we speak about the IT infrastructure used to arrange the operation of diverse tools and regular processes in the remote, end-user’s office outside the vendor’s premises. 
• SaaS – means Software as a Service and supposes that the cloud-based software vendor deploys it on its computing premises, supports it, and provides users with access to it as a ready-made web service. 
• PaaS – stands for Platform as a Service and consists of providing end users with a ready-to-use cloud platform for developing, testing, and deploying their own applications, from simple cloud services to end-to-end industrial systems.

Let's check these cloud service models in more detail.

IaaS Is about Infrastructure

When the IaaS access option is requested, users get numerous facilities –  servers, storage capacities, as well as network options, among others, –  to leverage them as if those could be available physically within their own premises. Overall, the IaaS meaning lies in ensuring steady connection between the end users and IT facilities; the latter ones are located in remote spots.

SaaS Is about Services

This is the most sought-after offer that supposes using apps that are hosted remotely. Based on individual credentials, end users obtain access to such tools to cope with regular personal or business tasks. In return, they pay a predefined price for a timeframe of leveraging SaaS (usually, this is one year or one month). Thus, SaaS meaning is to guarantee straightforward access to specific software under remote and subscription terms.

PaaS Is about a Platform 

It is a remote, cloud-hosted, platform aiming to produce, leverage, and support the operation of diverse apps. The facility holder owns all types of assets that guarantee steady operation. This is an all-in-one option comprising apps, systems, storage facilities, frameworks, functions, safety arrangements and protocols, backup copies, etc. PaaS meaning lies in forming a remote space where users can create, test, and run applications with specific functionality. For an oblivious reason, the PaaS variation is far cheaper in contrast when a user ensures all similar arrangements independently.

Public vs Private Cloud

But what about public vs private cloud – which of these options does each of the above models provide? A private option is entirely controlled by a single service provider without sharing the facilities with others. A public counterpart is offered to an unlimited number of external subjects who only intend to utilize specific offers. Most of the cloud providers are categorized as ones belonging to the second type.

But are there any intermediary options? Yes, there are hybrid cloud solutions, too, that are created and maintained on the so-called “edge” locations, i.e., thanks to both private and public facilities. 

SaaS vs PaaS vs IaaS: Distinct Features to Know

Each approach from the SaaS vs PaaS vs IaaS trio is associated with distinct peculiarities. We will look at them from the user’s perspective:

Choosing the Right Model for Your Case

When the story comes to making a choice, there are numerous pitfalls to take into account:

Bottom Line 

Leveraging software as a service is an efficient approach. It frees the assets owned by an end user and reduces one's expenses drastically. The single point is to have a clear overview of the project for which you request these external services. Therefore, you have to make a perfect match by saving this info with the comparison of sought-after models.

When you are going to create a new web solution from scratch or optimize an existing one, one of the key indicators of top high quality will most likely be a high response rate (to user actions) and SEO-friendliness. 

Unfortunately, client-side rendering, which is done by default in many modern web frameworks and libraries, can become an antagonist for developers pursuing these two goals. In this case, it makes sense to consider the possibility of implementing server-side rendering. Below, we will explain to you what it is, what its features are, with the help of which software tools it can be implemented, and also for which projects it is best suited. 

Definition of Server-Side Rendering

Generally speaking, server-side rendering (SSR), as is probably clear from the name, occurs on the backend side. First, the browser sends a request from the client side to the server, after which the SSR server returns an HTML page with all the necessary meta tags, styles, markup, and other attributes. Then, in the browser, the rendering itself happens, the results of which immediately become visible to the end user.

Why is all this necessary if you can use the default option, client-side rendering (CSR)? – you may ask. In fact, everything is simple: search engine crawlers do not recognize the SEO text contained on the pages (or the page, if it is the only one) of the CSR solution. Thus, if the CEO occupies a significant part of the promotion strategy of your project, you can achieve better results only by implementing SSR. Let us add that projects with sophisticated business logic may “suffer” from CSR in the context of performance since the increased load in the form of several synchronous requests will lead to delays in the interface’s response to user actions. And this is exactly the case where server-side rendering can also become a win-win solution.

Currently, SSR technology is actively used in such world-famous solutions as Airbnb, Upwork, YouTube, Netflix, Uber, etc.

What Are the Benefits of Server-Side Rendering?

Now, based on the above, let's look at the key benefits of SSR.

• SEO and social media friendliness. The server side render approach ensures improved SEO ranking through the correct indexing of pages – now, search robots can recognize SEO text and other attributes important for good ranking. First of all, this is due to the fact that now, search robots do not need to read SSR JavaScript code. As for friendliness for social platforms, it is explained by the ability to display colorful previews when sharing SSR-rendered pages – all due to the correct recognition of meta tags. 
• Better app/website performance. SSR rendering provides a faster initial page load as the JS to HTML conversion is done on the backend. Thus, users see refreshed content faster than with CSR, in particular when it comes to dynamically updated pages. In the long term, this can ensure a reduced bounce rate for websites and web applications. 
• Lower load on the user's device and better user experience (UX). Due to the fact that user requests are now processed on the server side, the user device will experience minimal load. All that remains for it is to interpret the HTML code returned by the server.

What Are the Risks of Server-Side Rendering?

To ensure the objectivity of our review, let's also analyze the disadvantages of server-side rendering.

• Higher TTFB. TTFB or time to the first byte is one of the highest priority indicators of good (or, vice versa, insufficient) performance of web pages. This parameter indicates the time it takes for the browser to receive the first byte of page data processed on the server side. Typically, compared to CSR, the TTFB value is higher because instead of returning a file with links to JS, the server spends some time converting JS to HTML code.
• Limits on the number of requests simultaneously processed on the server side. Due to the increased load on the server, the number of requests processed synchronously will be less than in the case of client-side rendering. Thus, the server throughput will be reduced.
• Need to wait for all the HTML code to load. While the page is loading HTML code under SSR, the user will not be able to perform any new actions on it.

If we add to the above disadvantages a fairly high entry threshold into SSR, as well as an increase in the budget of such projects (due to frequent requests to the server), it becomes clear that this approach is not suitable for everyone.

Server-Side Rendering Frameworks and Tools

As for the server side rendering frameworks and libraries that can be used to process client-side requests on the backend, these include React, Next.js, Nuxt.js, Angular (v7 and newer), and Svelte/Sapper. They use one of the most universal server-side templating languages – JavaScript.

Below we propose to consider server-side rendering React concepts only since React is one of the main tools that we use in web development.

Server-Side Rendering vs Client-Side Rendering

Server-side rendering is not a one-size-fits-all solution since there are situations where its alternative, client-side rendering, is the best choice. In particular, if the content on web pages is updated dynamically – that is, it requires the rendering of some components only (i.e., those with whom the user interacted) while the whole page doesn’t need to be updated, CSR is better suited since part of the content with which the user did not interact will be already loaded.

However, considering that during initial initialization, the content is not displayed until the page is fully loaded into the browser (this can take 2 or 3 seconds, which is critical for a modern consumer of Internet content), when implementing CSR, the site may have poor SEO regardless from the professionalism of SEO specialists (note that this is not a default situation, because with the right approach, lightweight projects with CSR are still ranked well). And this is where the SSR React approach can come to the rescue as usually, React server side components are well-recognized by search crawlers. Thus, by resorting to it, you will be able to ensure enhanced content visibility for search engines.

Server-Side Rendering: SEO vs. Performance

As you can already understand, server-side rendering is capable of providing the best SEO performance for solutions that really need it. In particular, thanks to this approach, search engines will not need to interpret JavaScript. At the same time, if you decide to render in React applying CSR by default, for the React server side rendering implementation, you will have to use additional tools to indicate metadata (for example, React Helmet).

As for performance, in the case of high-load projects, with the server side React rendering, this indicator will be better than with CSR since the SSR website or application will not be limited by the resources of the user device and browser. Also, the user device itself will be less loaded since its only task in the context of updating content will be its output (without rendering).

Conclusion

To sum up, we would like to emphasize that with the correct use of JavaScript frameworks for SSR, you can solve the problem of poor ranking of single-page applications (SPAs) as well as content-heavy websites where SEO and bootstrap performance are critical. On the other hand, CSR is suitable for software with dynamically updated content, that is, content that should change without completely refreshing the page.

However, you should not limit yourself to just these two rendering approaches. In particular, there are also hybrid rendering approaches that combine the best characteristics of SSR and CSR. For example, you can consider the static site generation (SSG) vs SSR couple – perhaps the first option will be the best choice for your project.

‍

Hey, are you here to find a solution for a consolidated and easy-to-access “home” for your business information, which is usually transferred from different places, often unrelated to each other? Then, you probably need to think about creating a digital space where it will be integrated, cleaned, structured, and stored accordingly, for further use in your regular business operations. But what is this space? Let’s find it out right now.

What Is Data Warehousing?

In a nutshell, it is a repository where your business data comes from disparate sources, where it is brought to the proper quality, and where it is stored, providing individuals with the appropriate rights with easy and fast access to it. Typically, such repositories serve as one of the central components in automated analytical solutions, but, as practice shows, the range of their application can be much wider.

Key Components of a Data Warehouse

In general, its main components are considered to be the following:

• Sources, from which structured and unstructured information comes – these can be third-party databases, tables, systems, applications, etc.;
• Data Extraction, Transformation, and Loading (ETL) tools, which define scenarios for extracting, transforming, and loading the information;
• Data warehouse database, which is the main repository (usually in the form of a database management system, DBMS) with already prepared, i.e., cleaned and structured data, that can be used for analytics, reporting, and other business tasks without additional manipulation;
• Metadata repository, which includes the permissible data types and the rules according to which this data will be used;
• Query and reporting tools, which define algorithms for fast and unified access to data, as well as its analysis;
• Data mart, a subset of the data warehouse that is used for individual business tasks (this can imply, for example, marketing data warehouse design) which formation occurs either directly through the collection from disparate sources or pre-preparing within a consolidated space.

Core Principles of Data Warehouse Design

Now, let's talk about the main data warehouse design principles:

• A clear definition of business requirements and goals, as well as metrics that allow you to objectively assess the degree of their achievement;
• Understanding how information is integrated from multiple sources and what should be the unified format after its transformation;
• Choosing the right type of data modeling – these can be star schemas, snowflake schemas, fact tables, and so on;
• Choosing the right methods and data warehouse software to ensure the quality and consistency of information, in particular, the methods of cleansing, validation, and supplementing of data;
• Planning, scaling, and managing the performance through various methods of indexing, partitioning, compression, etc.;
• Choosing the right tools for metadata management to simplify and improve access to the information;
• Ensuring security and access based on policies and rules (usually, this is achieved through the implementation of advanced encryption algorithms, the introduction of access policies for different user groups, as well as providing reliable authentication and authorization methods);
• Implementing end-to-end monitoring for ensuring data quality and security, performance of processes occurring within the data warehouse, and so on.

Steps in Data Warehouse Design

In this section, we invite you to consider the key steps leading to a successful and agile data warehouse design.

Requirement Gathering

According to the principles to design a data warehouse we defined above, the key to effective data warehouse design is to gather business requirements and clear business goals that it should fulfill. It is also important to identify the requirements for security, scalability, and performance of the repository.

Data Modeling

This is not yet a practical stage, but it still requires the participation of specialists – in particular, it implies the identification of entities, their attributes, as well as possible relationships between them. After this, the most suitable type of DBMS implementation needs to be selected – for example, in the form of tables, columns, indexing, etc. After this, you have to make sure that the selected type performs all the tasks assigned to it according to the predetermined requirements.

ETL Process Design

We have already explained above what the ETL process means, and this stage actually involves choosing the right tools and scenarios for their use.

In particular, you will need to define methods for extracting information from disparate sources (these can be database queries, API calls, file transfers, etc.), methods for bringing data to a single format and ensuring its proper quality (since you will most likely have to deal with big data, there may be many inconsistencies), methods for aggregating data to create complex information structures, automation methods for bulk loading of data (this can be full or incremental loading, and so on) with the usage of temporary storage areas, methods for detecting and eliminating data errors, as well as methods for checking data for completeness and accuracy.

Database Schema Design

There are several well-known data warehouse design patterns, such as:

• Star, which has a fact table at its center and dimension tables associated with it around it;
• Snowflake, which is a more complex Star and also implies additional dimension tables that surround each base dimension table;
• Galaxy, which contains two fact tables and the dimension tables between them.

Data Integration

Now, you can start integrating the data using the previously defined ETL tools and technologies. At this step, you need to make sure that everything works as intended, and the data is transformed into the required unified format.

Data Storage Solutions

At this stage, you need to choose specific data storage solutions according to your requirements for the expected data volume, performance, scalability, and cost. Usually, the choice is made between relational databases, columnar databases, data lakes, and cloud data warehouse solutions.

Data Presentation Layer

Finally, to design data warehouse, you will need to understand what your data presentation layer will be – the layer at which end users will be able to seamlessly access the data and use it to solve specific business problems. This includes developing interfaces, dashboards, reports, and various data visualization tools.

Conclusion

Now that you have a clear guide to data warehouse design, you can begin implementing it with a full understanding of the principles and stages on which it is based. If you would like to delegate this comprehensive task to seasoned data warehouse development specialists, just contact us.

The first question that you should ask yourself before contacting the IT outsourcing company is “what billing model is the best fit for my project?”. If you are confused about choosing an outsourcing model from the Dedicated team vs. Fixed price vs. Time and Materials for your business idea, then welcome aboard!

In this article, we will compare these business models for your project. Let’s analyze each in detail and describe the advantages and disadvantages of 3 main IT outsourcing models.

Fixed price

The fixed-price agreement is a single-sum contract where the software development team must deliver the project within a predefined sum which is agreed by both parties. A client should be able to share his clear vision of the product with developers to ensure appropriate final results. This model requires the client to provide a detailed list of requirements for the project and all required developer documentation.

Pros of fixed price model:

• Clarity. Project requirements are agreed upon before signing the software development contract, as well as all the required developer documentation is specified beforehand.
• Accuracy. The project scope and time frames are known and discussed in advance, so the team can set the deadlines, and it is convenient to monitor the project progress.
• Autonomy. The development process is coordinated by a project manager, so the client’s participation isn’t necessary.

Cons of fixed price model:

• Preparation. The period is needed as all requirements for implementation and deadlines must be documented.
• Inflexibility. Any change in the scope of work would cause a change in the total cost of the project and this change would be compensated by the service provider’s end.
• Risks. If you don’t provide your requirements correctly, then the delivered product won’t be the same as expected.

When is recommended to use a fixed price model:

• Clear requirements and determined deadlines.
• Limited or fixed budget.
• MVP.
• Small and medium projects with limited project scope of work.

Time and Materials

Time and materials contract is absolutely different. This model is great suited for long-term projects with changing requirements, where the final requirements are not known in advance and can be changed on the go. This is a flexible approach to IT outsourcing, as the customer pays in smaller chunks for work accomplished during the billable hours. To say more, this pay-as-you-go model allows you to pay only for the work actually done. For example, for features delivered, milestones, etc.

Pros of Time and Materials model:

• A flexible approach. The customer can change the scope of work, requirements or add/drop features on the go to meet his business aims without thinking about the budget. This model perfectly combines with modern agile methodologies, for example with Scrum.
• Transparency. This model allows the customer to control the cost and concentrate on important elements of the project. The client pays only for the results actually delivered.
• Involvement. The client can monitor the process of the development of a certain work schedule in accordance with the expected results.

Cons of Time and Materials model:

• Budget and time. It is not always possible to estimate the budget in advance. It’s hard to predict when the product will be delivered or how much it will cost. This depends on the accuracy of the specifications or its changes in the process of work;
• Communications. To achieve a high-quality product, continuous communication with the team is necessary. It requires full-fledged involvement from your side, which includes spending much time in communication with the development team.

When is recommended to use Time and Materials model:

• Long and middle term projects with dynamic requirements;
• Project scope is not fully known;
• The customer wants the flexibility to modify the project scope.

Dedicated team

The Dedicated Team model is used to compensate for the lack of in-house IT expertise on mid-to-long-term projects. The billing is based on hourly rates of the developers, and they become a part of a team that is only concerned with the project and not engaged in any other tasks. The developers report directly to the client. However, the client is responsible for team management and control.

As an example, let’s say the client wants to develop software that is not in his team’s expertise, he can hire a developer or team who can do this. In this case, the client can outsource to an experienced team that can help him fulfill his customer’s needs by creating rich quality projects. This will enable the client to maintain stability between your team and the dedicated team.

Pros of Dedicated Team model:

• Control. The customer is provided full control and management of the team. Cooperation between the client and the team is very important because it allows for effective planning and evaluating the strengths and weaknesses of the work process.
• Development. When a team is focused on one project, it ensures the best results. The team has a full understanding of all project features and is dedicated to running the project smoothly.
• Progress. The ability to optimize the product is important for product growth. With the dedicated team, it is much easier.
• Reduced costs. The remote team solves many problems with the recruitment and hiring of staff. Plus, you always know the next month’s payments and taxes.

Cons of Dedicated Team model:

• Thoroughness. The client must consider process planning and task distribution for every member of the team.
• Engagement. You might have to invest more time in communication, discussion and software development.
• Graduality. Looking for the perfect candidate takes a lot of time and the client has to be involved in hiring team members.

When is recommended to use Dedicated Team model:

• For long-term IT projects with rapidly changing scopes.
• Adding more workforce to set up a strong development team.
• When you want to access cross-border expertise and knowledge sharing.

Conclusion

To sum up, every project provides the best results when it is managed according to the most suitable IT outsourcing model. Each software product development pricing model has its pros and cons. Choosing the best possible approach fully depends on the specifics of your project and expected results.

According to this, the first step is understanding your business model’s requirements. After determining your project’s needs, you can select the right outsourcing model and start with it.

Interesting fact: there are approximately 8,462 project management methodologies to choose from. Every project manager understands that selecting the right methodology is crucial to getting the job right.

So, how to understand which one is right for your project?

There are many various ways to deliver projects. Generally speaking, these ways are our project management models – applying different principles, themes, frameworks, processes and standards to help provide structure to the way we deliver projects.

Agile is one of the more recognizable project management methodologies. This methodology is best suited for projects that are iterative and incremental. It’s a type of process where demands and solutions evolve through the collaborative effort of self-organizing and cross-functional teams and their customers.

Agile is a methodology that has methodologies within itself, such as Scrum and Kanban. Scrum methodology is one of the most popular and simple frameworks to put the principles of Agile into practice.

Let’s talk about the Scrum and how it works

Scrum is a subset of Agile. It is a framework for agile development that helps teams work together with the customers. Much like a sports team training for the big game, Scrum encourages teams to learn through experiences, self-organize while working on a problem, and reflect on their wins and losses to continuously improve. Its goal is to develop, deliver, and sustain complex products through collaboration, accountability, and iterative progress. According to this, it is not surprising that Scrum is the most widely-used one among the teams.

Scrum team roles

• Product owner: The product owner represents stakeholders, which are typically customers.
• Development team: Group of professionals that consists of three to nine individuals who have the business, design, analytical and development skills to carry out the actual work, solve problems and produce deliverable products.
• Project manager: Manager who ensures the understanding and execution of Scrum is followed. The manager’s responsibilities include coaching and motivating the team, removing impediments during the development, and ensuring that the team has the best possible conditions to meet its goals and produce deliverable products.

Phases of Scrum Model

Now, let’s take a look at the main steps of the development process that Scrum consists of.

Step 1. Product Backlog Creation

A product backlog is a list that contains features to be implemented during the development process. It’s ordered by priority and every item is called a User story. A user story is an informal, general explanation of a software feature written from the perspective of the end user or customer. It helps development teams capture simplified, high-level descriptions of a user’s requirements written from that end user’s perspective. The examples below show how these stories can look like:

• As an internet banking customer, I want to see a rolling balance for my everyday accounts, so that I can keep track of my spending after each transaction is applied

• As a manager, I want to be able to understand my colleagues’ progress, so I can better report our success and failures.
• As a customer, I want to receive an SMS when the item arrives, so that I can go pick it up right away.
• As Max, I want to organize my work, so I can feel more in control.

This structure is not required, but it is helpful for defining done.“Why can’t we just write features or tasks instead?”

Step 2. Sprint Planning and Sprint Backlog Creation

The sprint duration is very important so that the user stories are as small as possible. The typical average sprint duration lasts about 2 weeks. If the sprint duration is small, then the advantage is that more customer feedback can be received and most of the errors and bugs can be addressed earlier. If the sprint duration is long, then it allows the developer to work thoroughly.

The next stage is to do the sprint backlog creation. It consists of user stories that will be completed during the current sprint. The scrum team must select the important user stories and make them into smaller tasks. They need to plan on how to get the task completed. The Scrum team should be capable of finishing all these stories on time. Also, one important thing is to prioritize the necessary tasks.

For example, the goal for Sprint: “A website visitor can order a product”. We discuss with the team and product owner how to implement this. Roughly, customers have to go through three steps to order something: 1) select a product, 2) enter address and billing information, 3) perform the payment. We discover several exception paths. After the discussion about what technology we will use for this goal and how the team will implement this functionality, we start creating the Sprint Backlog.

Below are some of the items that can end up on the Sprint Backlog:

• When an order is placed, send an email to the sales department;
• Allow customers to pay for their order by credit card;
• Encrypt user information in order (e.g. email, address);

Step 3: Working On Sprint and Scrum Meetings

The actual user stories are moved as small tasks in the sprint backlog, where the actual work starts. This is where the implementation of a software application, such as website development, begins.

To begin with, a task board is made with a lot of cards is used. The cards specify the details about the tasks such as assignee, work details, due date or the time duration, etc. The cards can be arranged according to their importance. When work on a task has been started, the corresponding sticker is moved from the “To do” field to the “In progress” one. When work is completed, the sticker can be moved to the “Testing” field, and after the task is successfully tested, the sticker goes to the “Done” field.

For this activity, we use specialized software JIRA and Trello for this task.

In this step the scrum meetings are important as it is done to track the progress status and who is doing what status. The burndown chart is the output of this meeting, as it provides the details about how many tasks are completed and if there are any issues or problems in completing the tasks in the “Work In Progress” columns.

It is also important to notice one more Scrum feature is Daily Scrum meetings. These meetings’ main purpose is to get full information about the current project status and make sure that all team members are on the same stage. During Scrum meetings, every single team member should tell what he has done for the day, which tasks will be the next, and what problems team members faced during the work.

Day by day Scrum meetings help increase the flexibility of the development process. They also allow understanding of what changes should be made.

Step 4. Testing, Product Increment and Sprint Review

The result of every sprint in Scrum is a potentially shippable product increment that can be presented to the customer. After each iteration, the development team creates a new version of a software product and adds new features with increased value. In the end part of every sprint, there is Sprint Review where the overall results can be demonstrated and analyzed. According to this info, the stakeholders can make a decision about further project changes and plan the next sprint.

Step 5. Retrospective and Next Sprint Planning

Retrospective’s main goal is to consider the results and the ways how to improve the development process on the next step. The team should talk about the lessons learned and the pitfalls that were during the development part. An important feature is to improve the work of the Scrum team as a whole. The team should conclude what went well during the working process and what can be done better during future iteration. When the ways of improvement are defined, the team can start and concentrate on the next sprint planning.

Project Closure

The project closure phase represents the final phase of the project management. Around this time, the final product is ready for delivery. Here, the main focus of the project manager and the team should be on product release and product delivery. In this stage, all the activities related to the project are wrapped up.

Once the product is handed to the customers, the documentation is finalized and the project is closed.

Conclusion

The main differential features of Scrum are flexibility and constant progress. It’s provided mostly by regular communication and close cooperation between the stakeholders at each step.

When the sprint is done, the customer can assess the working product functionality at the current iteration and make decisions about how the project should evolve during the next sprints.

Use Case: Web Development

Problem Statement: Important changes need to be implemented on an existing company website.

Scrum team roles:

1. Product Owner: Team Lead
2. Development Team: Developers
3. Scrum Master: Project Manager

Basic Flow of Events:

1. The website needs to be updated.

Using Scrum:

1. Product Owner creates a backlog, i.e. the prioritized changes to make.
2. The development team and the QA team is created.
3. Sprint of 7 days is decided.
4. Project manager is assigned to set up the meetings and help with issues.
5. Tasks are assigned to the team
6. A daily 15-minute Scrum is set up for holding team meetings
7. The website is updated each day with the work done
8. QA notifies issues on the same day
9. Each week, the Sprint Review meeting is held with the CEO for an update on progress

Scrum is best suited for projects that consist of teams of less than seven people who need a flexible approach to deliver a product or service.

As the practice shows, no idea, even the most brilliant one, when embodied in a digital product or service, will become successful without quality assurance. It, in turn, always includes two non-intersecting procedures that occur before software is launched: the first of them is aimed at obtaining a clear understanding of whether development is moving in the right direction, and the second of them clarifies whether the solution being created meets end user needs. So, how are they called and performed? Let’s find it out right now.

What Is Verification Testing?

In a nutshell, it is a procedure aimed at checking whether the solution being created meets its predefined specifications and generally accepted design and development standards. Software verification testing is performed throughout the entire creation process and involves the use of various automation testing tools and verification methods, such as modular, integrational, and system testing.

What Is Validation Testing?

Unlike the previous type of testing, this one involves planning real-world scenarios that allow the development team to make sure that the solution being created meets its audience’s needs (for this, you can apply, for example, the alpha- and beta-testing validation methods). After that, the solution has to be compared with its specifications. If any discrepancies are found, they need to be eliminated before this solution is released to the public. Actually, that’s why validation testing is repeated until the team achieves full compliance.

Purpose of Verification and Validation

The main goals of verification and validation testing are to fully satisfy the needs of the software solution owner and the audience as well. As soon as these procedures are successfully completed, the project can be launched.

Difference Between Verification vs Validation Testing

So, what about the verification and validation difference? Generally speaking, while verification is aimed at checking the compliance of a product or service with its list of requirements agreed upon between the development team and the owner, validation allows teams to make sure that this service or product will be positively accepted by its end users. 

In this regard, the first procedure starts from the very beginning of the development process and lasts until the final testing stage and the second – only after the product/service is completed. This also imposes certain differences on the test data used: during verification in software testing, QA engineers use sample data (in this regard, automation methods are often applied), and during the software validation – real data (usually, manual methods do a great job here).

How Are Verification and Validation Testing Performed?

Now, let's look at the four most popular approaches used for validation and verification in software testing:

• Peer reviews, which involve providing a software solution to focus group representatives for a certain period of time in order to obtain feedback on their experience of interacting with it;
• Assessments, which are left by focus group representatives after checking the solution for functionality and identifying errors and inconsistencies in it;
• Walkthrough, which implies a preliminary explanation to focus group representatives of how exactly to interact with the software solution, after which the latter leave their feedback on how well everything was clear and whether they think some areas need to be optimized;
• Desktop-checking, which includes reviewing the software code by specialists (in particular, software engineers).

Tips for Successful Verification and Validation

To ensure these two procedures go smoothly, follow these guidelines:

1. Define the tasks and goals you are pursuing through these procedures and what the results should be upon their completion;
2. Choose the specific tools and approaches you are going to use – they should cover all possible scenarios of user interaction with your software solution, as well as generally accepted software development standards;
3. Create a testing plan, where you will specify deadlines, available resources, and evaluation criteria (along with the acceptable minimum compliance);
4. Proceed directly to testing in order to identify bugs and inconsistencies that will need to be fixed before the project is released;
5. Involve representatives of the potential target audience and stakeholders in the testing procedure to get the most objective assessment of the quality of your team's work;
6. Don't forget to document and monitor the testing results from one bug fixing to another to understand the dynamics of improvements.

Popular Test Automation Tools For Verification and Validation

Although automated testing is considered a standard approach for verification testing only, sometimes, it also brings benefits when implementing validation testing. In this regard, we have compiled a small selection of popular tools that you can use for quality control in software:

• Selenium, an open-source web solution that supports a lot of programming languages, such as Java, Python, C#, and so on, as well as integrates with different frameworks;
• Appium, an open-source service for automated testing of mobile apps on iOS, Android, and Windows (both native, cross-platform, and hybrid ones);
• Robot Framework, an automation framework aiming at implementing acceptance testing and acceptance test-driven development;
• Jenkins, an automation server used for continuous integration and continuous delivery that streamlines the build, test, and deployment stages;
• TestNG, a popular testing framework that is actively used for testing Java-based software solutions;
• Cucumber, an environment for running automated acceptance tests written in Java, Ruby, etc.;
• JMeter, a perfect solution for performance testing of web apps.

Conclusion

We hope that we have helped you understand the difference between validation and verification testing, and now, you can also assess their importance in creating high-quality and competitive software solutions. You can also check out our blog to learn more about software development and design.
