Planning to launch a software application that is of the highest strategic importance to your organization? If you are then you will need a great app development team.
If you are reading this then you are wondering how to build an app development team. DevTeam.Space has put together this guide to help you.
Let’s first understand what it takes to build great software product development teams.
How do You Build a Dev Team?
You will do the following to build an efficient application development team.
1. Analyze your project scope, e.g., web development, mobile development, etc.
Have thorough discussions with product managers and other business stakeholders to understand the project scope. Your project might involve one or more of the following:
- Web development;
- Developing native apps for Android and iOS;
- Building cross-platform or hybrid apps;
- Creating an Artificial Intelligence (AI)/Machine Learning (ML) system;
- Developing a blockchain app;
- Executing a data science project;
- Building an IoT (Internet of Things) app.
Plan for hiring a team based on your project scope.
2. Consider various choices for building a software development team
Wear the hat of a strategist and decide what you want as far as a software development team is concerned. Your next steps depend on the clarity you gain during this stage.
You have the following options:
A. Hiring freelancers
Many startups don’t have enough developers in-house. They might not be able to afford a high lead time for hiring, furthermore, they might have budget constraints.
Do you find yourself in this situation? You might think of hiring freelancers from one of the freelance platforms.
The entire responsibility of screening the candidates falls on you. This includes checking their LinkedIn profile, reviewing their project portfolio, conducting interviews, etc.
You might find developers at a low hourly rate. This approach might work for relatively simple projects like e-Commerce website development. However, we don’t recommend this approach for complex projects.
You will find it hard to manage a complex project with part-time freelancers. Freelance platforms don’t offer any management support.
You need to find replacements if freelancers leave your project mid-way. Differences in time zone can make it hard for you to manage the work of a freelancer.
Hire expert developers for your next project
B. Hiring people from a trustworthy software development company
We recommend this approach if you have a complex project. Trustworthy software development companies offer full-time developers. They can also provide QA (quality assurance) specialists, UI designers, etc.
Reputed software development companies regularly encourage their developers to upskill themselves. As a result, developers have higher motivation.
Trustworthy web and mobile app development companies provide management support. They provide replacements in the case of turnovers.
C. Outsourcing the entire software development process
This approach differs fundamentally since here you aren’t looking to fill development team roles anymore. You want a software development company to deliver your project from end to end.
You won’t monitor the work of various application development team members like programmers, testers, etc. The software development company needs to have experienced project managers (PMs) to oversee the project.
You provide the business requirements, and you evaluate software development service providers.
You typically use a structured procurement process including RFP (Request for Proposal), proposal review, etc. The selected service provider enters into an outsourcing contract with you. You govern that contract.
This approach eliminates the software development-related tasks for you. However, you lose control over the project execution. You need regular reviews to understand the progress of the project.
3. Review the roles you need to hire, e.g., project managers, programmers, etc.
Which software development team roles do you need? Specify this during the hiring process. Mention the experience level required. If you need experience in a particular industry, specify that.
You might need several of the following roles:
- Project manager (PM): You need this in nearly every project unless you have an experienced PM in-house.
- Software architect: Specify what kind of software development experience you need, e.g., web development, mobile development, blockchain, etc.
- Business analysts: Specify any industry experience that you need.
- Web developers: Mention the level of experience you need.
- Mobile developers: Specify whether you need native or cross-platform mobile app developers.
- Testers: Mention your requirements, e.g., functional testing, test automation, performance testing, security testing, etc.
- DevOps engineers: Specify your choice of DevOps tools.
- AI/ML developers: Specify whether you want programmers to develop AI/ML algorithms from scratch.
- Data science project roles: Data science projects involve roles like MIS reporting executives, data analysts, DBAs (database administrators), statisticians, ML engineers, data scientists, data architects, and big data engineers.
4. Determine your skill requirements
Your skill requirements depend on your project scope. The mapping of skill set requirements with the project scope are as follows:
A. Native android development
If you undertake a native Android development project, then you need a mobile app developer with the following skills:
Programming languages like Java or Kotlin
Java and Kotlin work optimally with the Android operating system. Both are powerful languages with extensive features.
Developers can gain productivity, and both languages prevent common coding errors. Java is more popular. Kotlin is a relatively new language.
Material Design guidelines
You need developers that understand the Material Design guidelines very well. Android apps need to comply with these guidelines for the user interface (UI) design.
Tools and resources
You need programmers that know the following:
- Android Studio, the popular IDE (Integrated Development Environment) for native Android development;
- Espresso, the popular tool for testing Android apps;
- Android developer documentation for publishing Android apps.
B. Native iOS development
You need programmers with the following skills for native iOS development:
Programming languages like Swift or Objective-C
Objective-C was the mainstay of iOS development for a long time. Apple now prefers Swift, a more modern language.
Both are feature-rich languages. They work well with Apple’s platforms like iPhone, iPad, etc. However, Swift offers excellent productivity to developers. It also prevents many common programming errors.
Human Interface Guidelines
Apple requires UI designers to use Human Interface Guidelines for app design. To deliver the right user experience, iOS developers should know how to code in line with these guidelines.
Tools and resources for iOS development
You need developers that know the following:
- Xcode: It’s the popular IDE to develop apps for Apple’s platforms.
- XCTest: iOS developers should use this popular framework for testing.
iOS developers should know the process to submit apps to the Apple App Store.
C. Cross-platform mobile development
Cross-platform mobile development involves one codebase to execute the app on both iOS and Android. This approach can reduce development and maintenance costs.
It can’t match the native user experience, performance, and security fully.
React Native, a modern cross-platform mobile framework can provide a near-native user experience.
Flutter is another popular cross-platform mobile framework coming close to the native user experience. Look for mobile developers with these skills if you opt for cross-platform development.
D. Web development
Technology stacks like MEAN (“MongoDB-Express.js-Angular-Node.js”) and MERN (“MongoDB-Express.js-React-Node.js”) are popular.

F. AI/ML development
You can take any of the two approaches for AI/ML development. These are using an AI platform, and developing AI/ML systems from scratch, respectively.
You can use an AI/ML platform and reduce some of the coding work. This approach works very well if you have standard requirements like creating bots, making product recommendations, etc.
Look for developers with experience in top AI/ML platforms, e.g.:
- Google Cloud AI;
- Amazon AI services;
- Microsoft Azure AI;
- IBM Watson Studio;
The second approach involves creating AI and ML algorithms from scratch. This approach involves more complexities, and you need experienced programmers.
Look for Python developers. Python offers excellent libraries to make AI/ML development easier. You should expect developers to know about the following libraries:
G. IoT development
You can take one of the two following approaches for IoT development:
- Using an IoT development platform;
- Developing an IoT system from scratch.
The first approach reduces the coding work for your team. Look for programmers that are familiar with the following top IoT development platforms:
- Google Cloud IoT;
- Cisco IoT Cloud Connect;
- Salesforce IoT Cloud;
- IRI Voracity;
- IBM Watson IoT;
- Amazon AWS IoT Core;
- Microsoft Azure IoT Hub;

The second approach involves more coding. Look for developers with the following skill sets:
- Application security;
- Big data tools;
- Cloud computing;
- AI/ML development.
H. Blockchain development
Are you undertaking a blockchain development project involving a public blockchain? We recommend you develop it using the Ethereum blockchain platform.
There’s a rich ecosystem of Ethereum development tools. They help developers significantly. Look for Ethereum blockchain developers with Solidity skills.
Solidity is a proprietary language of the Ethereum project team for smart contract development. Ethereum developers should be familiar with other development and testing tools, e.g.:
- Ganache, an Ethereum client;
- Truffle, a tool to organize and deploy smart contracts;
- MetaMask, a browser extension, and crypto wallet;
- Remix, an IDE to code smart contracts;
- Ropsten, a test network to test smart contracts.
If you plan to develop a private blockchain system, then we recommend Hyperledger Fabric.
This open-source enterprise blockchain framework offers many advantages. They include modular architecture, pluggable components, tooling support, etc.

6. Induct and form your app development team
After you select suitable developers, you need to induct them into your project. Form a team that focuses on delivering sustained value to end-users via a successful app.
We recommend you use the Scrum framework for this. Scrum teams demonstrate a high degree of empowerment.
Software development team members work closely with users. While they use the required processes, they don’t allow overheads.
You need to provide the required documents to the newly formed team. Explain the project background to the team members. Describe the project environment and project plan. Talk about the business requirements in detail.
Provide the required access to the new team members. Introduce the new team to your larger team. Establish a communication process. Set up a thorough review process, and establish accountability.
The software development team structure might vary as follows:
A. Mobile development team structure
A mobile application development team should have a UI/UX designer, Android, and iOS developers, and testers working closely. Set up a small cross-functional team.
We recommend you use Scrum practices for the mobile app development process. The team should conduct daily stand-up meetings to discuss and resolve the project issues.
Developers and testers should collaborate to expedite the defect resolution process.
B. Web app development team structure
We recommend you form a cross-functional team including web developers and testers. The team should work closely with the “Product Owner”, a key role in the Scrum framework.
The team should get requirements from the “Product Owner”. A Scrum team should estimate the requirements and schedule them into different “Sprints”. Sprints are iterations in the Scrum parlance.
The PM should perform the role of a “Scrum Master”. A Scrum team needs review sessions with the business stakeholders to review the app created during a Sprint.
This is called the “Sprint review meeting”. Business stakeholders provide approval for a Sprint in these meetings.
Scrum teams should conduct lessons-learned exercises after Sprints. These are called the “Sprint retrospective meetings”.
C. AI/ML development team structure
You might use different types of AI capabilities in your project. E.g., you might use deep learning, natural language processing, vision, speech, and more capabilities.
Such a project might require different developers working on different workstreams. However, the PM needs to integrate their work. This requires adequate communication and collaboration.
Developers also need to collaborate with testers and DevOps engineers. The team structure should prevent silos, and the PM needs to foster open communication.
D. Data science project team structure
Apart from a PM and data scientist, data science projects require different roles like DBAs, data architects, big data engineers, ML engineers, data analysts, etc.
The PM needs to provide overall leadership to this team. However, the data scientist needs to provide leadership for certain aspects.
A data science project involves many aspects, e.g., managing data, transforming data, eliciting business requirements, etc. The most important aspect is to conceptualize and develop a solution to cater to the business requirements.
Data scientists must lead this aspect. The team structure must foster close collaboration between the PM and the data scientist.
