However, working with an external team can be pretty daunting at first. It will help if you understand how to build an app development team from scratch, the different roles and responsibilities of team members, as well as the right team structure that will deliver high-quality cross-platform or native apps. So, how do you go about it? Here is a quick guide to help you get started.

Mobile App Development Team Structure

The mobile app team structure of your choice largely hinges on the complexity of your app idea, which is driven by intricate business needs. Nonetheless, a prevalent mobile application development organizational structure for a small to midsize digital solution looks like this:

2D/3D Artists

Quite rare, but sometimes a mobile app development team structure projects for building gaming or marketing applications require 2D/3D talents to create animated characters, as well as 3D product models. The talent can create these concepts using computers or by hand, as long as the end design is in line with the client’s business requirements. Prevalent skills of 2D/3D artists include game engine understanding, creativity, 3D modeling, as well as drawing and illustration.

Web3 Developers and Consultants

The race to a decentralized internet is tightening, and projects that want to stay in the loop often hire Web3 developers and consultants to build and deploy applications on blockchain networks.

Mobile App Development Stages and Team Roles

Now that you understand mobile app development team roles and responsibilities, how do they intersect at different stages of the entire development process? Well, this depends on the type of development process and the number of stages involved. Every development stage involves various team members or all of them altogether to focus on the core goal.

Here is a typical flow of app development project roles and responsibilities throughout the building cycle:

Stage 1 – Discovery

As the name suggests this stage involved revealing more information about the app in terms of the target audience, goals, the size of the team needed to complete the work, as well as features proposal. In other words, all panning takes place here with the supervision of the project manager. Other talents involved in the discovery phase include business analysts, UI/UX designers, and all developers.

Stage 2 – Idea Validation

Idea validation involves gathering any information that can back the application’s vision through experimentation. The goal is to come up with a future-proof digital solution, with risks anticipated and mitigated even before the development begins. Team members required to implement idea validation include business analysts, QA experts, project managers, as well as big data engineers for real-time, data-driven insights.

Stage 3 – UI/UX Strategy

The idea validation phase gives feedback and recommendations in terms of the app’s usability. This is followed by a UI/UX strategy to implement the feedback, as well as conduct in-depth research on focus groups to polish the user interface as much as needed. The mobile application development organizational structure in this stage includes a UI/UX developer and a QA engineer to ensure that the end product prototype is highly interactive before taking the same to pre-development testing.

Stage 4 – Design and Development

This stage is dominated by developers who write code to program features and build the product simultaneously. The product manager closely monitors the development process and ensures that the talents stick to the plan, as far as time-bound deliverables and quality consistency are concerned. The app at this stage is classified as a minimum viable product (MVP) that is feasible as the designed concept but with limited capabilities.

Stage 5 – Testing & Debugging

The app is refined and made ready for deployment at this stage. The QA engineer will hunt for possible bugs and fix them, as well as issue recommendations for improving the user interface. This can include proposing element redesigns or introducing new integrations altogether. The product manager also features at this stage to help the client understand the proposed changes and how they influence their organization.

How to Choose the Right Size of Your App Development Team

Now that you understand how a mobile application development team structure looks, how do you choose the right team size? From the above sections, you can notice that a typical project requires an average of 5 to 10 roles. The number of talents, hence the team size, to fill up these roles depends on several factors, such as:

The Size of the Project

The size of the project determines the completion time. A bigger, time-bound project would mean hiring as many talents as possible to build faster and simultaneously. For instance, you might need two backend developers to share task loads and reduce the time to market for your mobile app.

The Complexity of the Project

The size of the mobile application development team structure required to build a complex app is bigger than for simple apps. In the case of simple to medium apps, some developer roles can cut across various functions. However, for a complex app, you might need to hire specialist developers for particular functions to ensure that they program high-tech features.

Are You Building a Cross-Platform App?

Unlike native apps, cross-platform applications only require one team of programmers to build and maintain them. That said, you might not need to hire as many roles as you would for both Android and iOS development. Besides the programmers, you’ll only need a project manager, UI/UX designer, and QA specialist.

Do You Have an In-House IT Department?

You might not need a bigger mobile application development team structure if you already have an in-house department for your IT smartphone products because this changes your outsourcing needs. For instance, your project might only require outsourcing a part of it, such as manual and automation testing.

How Much Does it Cost to Build a Mobile App Development Team?

Although most team members in a mobile app company organizational structure will charge an average hourly rate of about $50, the true cost of building your dedicated team depends on several factors, such as:

Project Type and Scope

The more complicated your mobile app project, the longer it will take to complete. That means added costs, whether you are paying per milestone or hourly basis. Alternatively, to build faster, you can hire many developers at a steep price to build rapidly.

Cooperation Model

Working with freelancers will obviously cost lower than in-house and with a dedicated mobile app company organizational structure. Similarly, an outsourcing agency might also charge relatively affordably due to economies of scale. These agencies usually enjoy cheap labor from developing countries, which of course, come at the expense of quality.

Hidden Costs

The hidden costs of working with remote development teams depend on the hiring location. For instance, the local country might require you to pay extra costs in employee benefits as anchored in law. This can include bonuses, allowances, or even insurance.

Particular Tips to Create an Effective Mobile App Team Structure

Every business owner endeavors to build a mobile application development organizational structure that they can trust and enjoy long-term collaboration with. With that in mind, it will help if you employ various practical tips post-hiring to ensure that you save time by working with value-matched talents only that add value to your project. Ensure that you pay attention to:

Hiring Costs:

the goal is to hire a relatively affordable talent that doesn’t compromise quality simply because they charge less. Ensure that you discuss costs beforehand and agree that it won’t hinder quality consistency before signing the contract.


You can gauge a developer’s or any other team member’s level of expertise from their online ratings and reviews from other clients. This gives you an overview of how it feels or looks like working with the said talent.


You want to work with a mobile application development team structure that is easily accessible for real-time communication and collaboration, especially if you are going to build on consensus. That said, consider language barrier, geographic, and time-zone limitations.

Personal Preferences:

Know how to build an app development team and hire talents that embody your brand ideals, as well as personal preferences to ensure a smooth workflow. Unless you are comfortable with talent, don’t include them in your team.

Non-Disclosure Agreements (NDAs):

IP security is a concern when it comes to working with dedicated teams. Ensure that your team members sign NDAs so that they can have a legal responsibility in safeguarding your IP and trade secrets.
