We follow our agile process to deploy this app. We collect all requirements from client. After in depth analysis we present our solution to client. Client loved our process and gave green signal.
Where we divide system into small backlog task and given priority and complexity to each tasks.
We started with User App UI and parallel start work on web backend. After multiple UI iterations we finalize UI and start work on design of user web. We created task backlog and kept some complex modules like booking and warehouse modules to last and complete all other functionalities first. After completion of beta version we start in depth testing with our internal tester. We test app with 18-20 people first collect there feedback and implement some feedbacks as per client approval. After UAT we deployed our solution on Play store. We deployed both apps on playstore.
