10 Biggest Challenges When Developing An App
Wondering what the 10 biggest challenges when developing an app are?
You’ve come to the right place.
Jim Deters, founder of Galvanize, once said “Two guys in a Starbucks can have access to the same computing power as a Fortune 500 company”.
He was speaking about how much cloud computing has helped professionals everywhere. While new tools have helped make development easier, there are still many challenges to overcome.
Here’re a few amazing case studies of companies who hired DevTeam.Space to build their software products:
- DentaMatch – Healthcare Android and iOS App
- Photofy – Photo And Messaging Social Media App
- SideKick Education – Education Web App
The challenges of developing an app
We now review the 10 biggest challenges of developing an app, and their resolutions, as follows:
1. Finding the right project manager
Developers with the right skillset, development platforms, tools, and frameworks help significantly in app development. However, the most critical success factor is a competent project manager (PM), and it’s not easy to find one!
You need to hire a PM with the following skills and competencies:
- Subject matter expertise: Look for appropriate experience and credentials, such as “Project Management Professional” (PMP) certification.
- Emotional intelligence: In an environment as competitive as today’s software development industry, successful teams need emotional alignment with the organizational strategy. PMs should facilitate this alignment, utilizing emotional intelligence. Read about the importance of this in “Emotional intelligence and project management”.
- PM methodologies: PMs need proficiency with the modern PM methodologies like Agile.
- PM best practices: Expertise in PM best practices like scope management, quality assurance, stakeholder management, etc. is important. Our guide “Project management: 10 best practices” can help here.
- PM tools: Experience in using modern PM tools like Asana, Trello, etc. makes a key difference. Read “The 10 best Agile project management tools in 2019” for more examples of trendy PM tools.
2. Selecting the right SDLC model for the project
Each software development project is unique, therefore, selecting the right software development life cycle (SDLC) model is key. Examples of popular SDLC models are as follows:
- V-shaped model;
Read “What Is software development life cycle and what you plan for?” to learn more about these models.
Choosing the right model could be tricky, therefore, you need to think carefully, e.g.:
- Are you developing a core software system in an enterprise, e.g., ERP, CRM, etc.? Such software systems do not undergo changes too frequently. These applications deal with the core business operations in an organization. Upfront planning, definitive project scoping, etc. are important here. We typically call these as “Systems of Record” (SoRs). “Waterfall” is the right methodology for such development projects.
- On the other hand, if you are developing customer-facing apps like web or mobile apps, you will enhance them frequently. You typically launch a “Minimum Viable Product” (MVP) and get market feedback. Subsequently, you add features based on this feedback. These apps are called “Systems of Engagement” (SoEs), and Agile suits such projects. Read more about it in “Waterfall vs Agile: which methodology is right for your project”.
3. Forming a capable app development team
Having a capable development team is a key success factor, however, it can be hard to form one! Assuming you are undertaking a web and mobile app development project, you need the following roles in the team:
- IT architects: They need to choose the right architecture pattern.
- UI/UX designers: iOS UI designers should know “Human Interface Guidelines”, whereas Android UI designers should be conversant with the “Material design guidelines”.
- Web developers: Consider hiring js developers for web app development.
- Android developers: Hire developers with Kotlin
- iOS developers: I recommend that you hire Swift
- Testers: Consider hiring testers with experience in Espresso for Android testing, and XCTest for iOS testing.
Note: I have not recommended that you hire cloud platform architects, mobile backend developers, infrastructure architects, and DevOps engineers. The reason is that I recommend using managed cloud services, and more on this later.
4. Choosing the right software architecture pattern
After gathering the business requirements, you make key decisions for the first time when choosing a software architecture pattern. You need to get these decisions right, therefore, choosing the right pattern is important. There are several software architecture patterns, e.g.:
- Layered (n-tier) pattern;
- Event-driven pattern;
- Microkernel pattern;
- Microservices pattern;
- Space-based pattern.
Read more about these architecture patterns in “Large enterprise Java projects architecture”.
Think carefully before choosing a pattern. I will illustrate this decision-making process with the following examples:
- If you are developing a heavy-duty app like Netflix with clearly segregated services, microservices pattern is the right one for its scalability. However, ensure that you have clearly decoupled the services from each other. Read “10 best practices for building a microservice architecture” for more insights.
- Assume that you want to ensure that the business logic of your app never concerns itself with the UI logic. This is important for “Separation of concerns”, however, it’s hard to implement. Programmers might mix data access code with other code that performs calculations. Furthermore, you might tie yourself down to specific frameworks and database vendors, to manage dependencies. That’s not desirable, and “Clean architecture” is your answer in such circumstances. You can read “Clean architecture for Android apps” for more information.
5. Finding the right “Platform as a Service” (PaaS) provider
If you are an up-and-coming entrepreneur, you might not prefer an upfront high investment in IT infrastructure.
You need to find the right managed cloud services provide for your web app development, and this is where “Platform as a Service” (PaaS) providers come into play. I recommend that you use a PaaS provider since they offer the following advantages:
- They manage the cloud infrastructure, networking, storage, operating system, middleware, and runtime environment. You bring your code and data, which enables you to expedite your project.
- PaaS providers enable you to integrate database, DevOps, “Application Performance Monitoring” (APM) solutions, and auto-scaling solutions.
- You can easily integrate 3rd party APIs in your code when you use a PaaS platform.
- When you work with a PaaS provider, you don’t need to hire cloud platform architects and DevOps engineers. As a matter of fact, reputed PaaS platforms like AWS Elastic Beanstalk and Heroku make it really easy to use DevOps.
You can read “10 top PaaS providers for 2019” before you choose a PaaS provider.
6. Selecting an appropriate “Mobile Backend as a Service” (MBaaS) provider
One of the mobile app development challenges is the development and ongoing management of mobile backend. Most entrepreneurs are in a hurry to launch their mobile app in the market. They prioritize UI design and implementing the features. Mobile backend development and its ongoing management take time.
Using a “Mobile Backend as a Service” (MBaaS) provider allows them to offload the backend part. The advantages of using MBaaS providers are many, e.g.:
- MBaaS providers address cloud infrastructure, persistent storage, etc.
- Mobile platforms and devices are numerous, and this poses a complexity when developing mobile apps. MBaaS platforms simplify this.
- User management, security, push notifications, etc. are easier to implement when using an MBaaS platform.
- It’s also easier to scale the mobile app and integrate 3rd party APIs when you use MBaaS platforms.
- You don’t need to hire mobile backend developers and cloud platform architects if you use an MBaaS platform.
AWS Amplify, Google Firebase are some of the reputed MBaaS providers. You can find more examples of MBaaS providers in “How to choose the best Mobile Backend as a Service (MBaaS)?”.
7. Choosing the right programming languages and development tools
Using the right programming languages and tools is key to achieving the required productivity. The choice of languages and tools vary greatly depending on the kind of app you develop.

Assuming you are developing web and mobile apps, I recommend the following programming languages:
- Use Node.js for web app development: This open-source runtime environment helps in developing scalable and performant apps. Key features like streaming are easy to implement with Node.js, moreover, using NoSQL databases like MongoDB are also easier with it. A vibrant developer community has built thousands of excellent shared frameworks and tools for Node.js. I have described a few of them in “10 great tools for Node.js software development”.
- Code the Android app using Kotlin: A modern open-source language, Kotlin has a concise syntax, which helps in improving the productivity of programmers. Android developers can code fast, performant apps with it, moreover, the language facilitates bug-free coding. Read more about Kotlin in “Kotlin vs Java: which is the best choice?”.
- Develop the iOS app using Swift: Swift is the language of choice for iOS developers since it has powerful features that make them more productive. iOS apps coded in Swift are fast, and code is easy to maintain. Read about its advantages in “How to migrate your Objective-C project to Swift?”.
Developers look for robust “Integrated Development Environments” (IDEs) to achieve higher productivity. I recommend that you use the following:
- Eclipse or IntelliJ IDEA for web app development: For Node.js development using Eclipse, you need to install plugins, and you can find them here. Similarly, IntelliJ IDEA has plugins for Node.js development, and you can read about them here.
- Android Studio for Android development.
- Xcode for iOS development.
8. Finding the right testing solution
Selenium, Espresso, etc. certainly help in web and mobile app testing. However, Agile projects typically have releases every 2 weeks, and test automation can be a challenge with open-source tools and frameworks. Additionally, a wide range of browsers, mobile platforms, and mobile devices further increase the complexity.
To start with, I recommend the following solutions:
- Selenium: This is one of the most popular open-source frameworks for web app testing automation. Selenium WebDriver is a very popular browser-based automation suite.
- Espresso: Espresso is a popular framework for Android UI testing, and it works well with Android Studio.
- XCTest: It’s a very popular framework for iOS testing, and your testers can consult “iOS unit testing and UI testing tutorial” if they need guidance.
However, you still need to address the following:
- You need to bring your testing effort in line with the “Continuous Integration” (CI)/ “Continuous Development” (CD) requirements in an Agile environment.
- The test suite needs to across a wide range of browsers and mobile devices, in a parallel testing set-up.
- The testing team needs robust reporting and analytics.
For these, I recommend that you use the following solutions from Experitest:
- SeeTest mobile and web testing automation along with Selenium: Read more about it in “Overcoming the 5 most Common Selenium Testing Challenges with SeeTest”.
- SeeTest “Digital Assurance Lab Management”: This enables you to access a wide range of browsers and mobile devices on the cloud or on-premise.
- SeeTest “Grid Execution for web & mobile”: You can run your tests on multiple browsers and mobile devices simultaneously.
- “SeeTest Reporter”: This offers robust reports and analytics, covering relevant metrics like test coverage.
9. Making the project team productive
In the age of Agile software development, the traditional ways of working involving silos and centralized decision making are no longer effective. Making the project team productive requires a paradigm shift in thinking.
The solution lies in creating an environment where the team is empowered. My recommendations are as follows:
- You might work with a remote team, therefore, learn how to effectively lead such a team. Our guide “10 essential tips to managing remote employees” can help.
- Use the “Scrum” technique to manage the project.
- Form small, cross-functional teams called “Scrum teams”, where the PM performs the role of a “Scrum master”. The scrum master certainly makes decisions, but so do the team members.
- Scrum teams have designers, developers, and testers working together, thereby breaking silos.
- Such teams have documentation, but it focuses on what adds value to the client. An example is the “Product Backlog”, i.e. the document containing requirements, provided by the “Product owner”.
- Scrum teams have meetings, however, these are focused on “Sprints”, i.e., iterations that create fully functional products. Teams hold “Sprint planning meetings” to plan iterations, and “Sprint review meetings” to demonstrate the app and get approval for the sprint. A Scrum team also holds “Daily stand-up meetings” to track the project status.
- Instead of relying entirely on annual performance reviews, scrum teams have “Sprint retrospective meetings”, to learn lessons from a completed sprint.
Read more about scrum in “How to build a Scrum development team?”.
10. Measuring the progress of the project in real-time
With the onset of Agile, tracking the progress of a project has changed, as follows:
- Such projects use a wide range of tools to run builds, managing releases, etc. These tools produce a large volume of data, however, we need to get insights from the data.
- Project teams need to track Agile metrics, e.g., sprint burndown, velocity, lead time, cycle time, etc.
- For an Agile team to be successful, they must know their real-time performance at all times.
- With releases every 2 weeks, stakeholder management now requires meaningful status reporting much more frequently.
The solution is to use a real-time dashboard. Such real-time dashboard tracks Agile metrics real-time and provides actionable insights from project data.
This helps in keeping the team informed about their progress in real-time, moreover, stakeholder management becomes easier. I have earlier explained the importance of such dashboards in “How a real-time dashboard can revolutionize your eSports development process?”.
