Team Members Involved in a project

Business Analyst

A business analyst is someone who understands your project from the very beginning. They’ll sit down with you, ask you many questions, and try to get to the root of what you want to achieve.

From there, they’ll help define the KPIs of the project, create the architecture of your app, and lay out a plan for how to make your project happen. They’re always looking for ways to make things better and more efficient. And in the end, they’ll help make sure that you reach the goals that you set out to achieve in the beginning.

During the course of implementation, whenever a team member is stuck in building a particular logic or needs more clarity on a specific process, they reach out to the business analyst for clarity.

UI/UX Designer

A UI/UX Designer plays a crucial role in mobile app development. He focuses on 3 key things: to make the app attractive, intuitive, and easy to use.

He ensures that the client’s brand logo, font, and color preferences are reflected in the app’s design. By doing this, he creates a cohesive and consistent look that helps the app stand out.

In addition to the screen design, the UI/UX designer will also help in creating the other designing collaterals of the app including app store images, icons, splash screens, and much more. He adds the wow factor to the whole app experience.

App Developers

Up next are the mobile app developers! These are the people who take all of the UI/UX designs and turn them into functioning applications.

They work closely with backend developers to ensure that the relevant APIs are integrated so that the app can fetch and display the correct values.

App developers work closely with business analysts to add the correct business logic to the mobile app. This helps the app to align with the client’s vision and goals.

Project Manager

A Project Manager is responsible for managing the project from start to final launch. His 3 key responsibilities are ensuring: the project stays on track, client servicing, and team coordination.

A project manager manages the relationship between the client and the development team. This includes communicating with the client, capturing feedback, managing tasks, and reporting progress.


Testers play an important role in making sure that apps work well on different versions of Android and iOS. They test each of the app’s functions in detail to identify any bugs or errors.

Tester coordinates with the app developers to get these issues fixed. In other words, they help make sure that your app is flawless, performs well, and is secure and easy to use.

Mobile App Development Process

At Eiosys, we take pride in our meticulously crafted nine-step app development process. It’s a well-thought-out journey that guarantees a well-built application. Every stage, from the initial customer interview to the final maintenance and support, plays a vital role in sculpting your app into a masterpiece. 

We’ve designed this process to ensure that every element aligns perfectly, leaving no room for error. It’s a journey that lets us combine creativity with rigorous testing, which results in apps that not only meet but exceed your expectations.

Customer Interview:

It is the most basic yet crucial step of our process. This step helps us understand the vision of the client and the goal that they are trying to achieve from their application.

And if there is a situation wherein the client isn’t clear about their idea then we consult the client and help them gain clarity on their project.

Scope Analysis:

Once the idea behind building the app has been conveyed properly, we identify our team members who would be working with you on your project. In this step, we also curate the documentation that will help us while developing your app.

The documentation ensures that everyone is on the same page with regard to the progress of the project. We also define the milestones and timeline for the project in it.

UX & Wireframes:

The designs and wireframes for each app screen are created along with the flow of the app. This is shared with the client for approval and feedback. This step also helps to define the entire user experience.


Based on your inputs and your preferences, or your brand guidelines (if you have one), we start developing the various elements for the user interface. We prepare the deliverables which would be appealing for your clients.

We’re considered as the top mobile app development company in Mumbai when it comes to UI & UX designing. Our UI designs are intuitive and simple to use. We empathize with the target customer while designing the UI.


In this step, the team starts to code the app. We use an agile methodology for the implementation of the project. The project is implemented in multiple sprints, each having a well-defined goal. At the end of each sprint, the progress is shown to the client.

Optimization & Polishing:

All the developed units are optimized and polished to ensure consistency. Additionally, the mobile software is also optimized so that it can work properly on different versions of the mobile operating systems.


The modules are individually tested for loopholes and bug fixes. We have defined in-house quality assurance standards for mobile app development.

Only once those standards are met satisfactorily, the app is shared with the client for final approval and validation.

Product Launch:

After the mobile application is approved by the client, we proceed with its deployment on the Google Play Store or Apple App Store.

We ensure that the app is compliant with the protocols put forward by the respective app stores. Finally, the app is launched.

Maintenance & Support:

Once the mobile app is launched successfully, we enter the maintenance & support phase. In this phase, we ensure that the mobile app runs smoothly in the latest versions of the operating systems.

We also undertake the task of fixing bugs in the application and making small changes in it based on the client’s preferences.
