When we get the requirements from the client we understand the requirements completely by scheduling multiple meetings.
Further, wireframes and prototypes are prepared to give a visual idea of how the various screens and elements of the mobile app are going to gel together and transition from one section to the other. This is like using the actual app, but on the paper or on the graphic screen rather than the actual mobile app.
Based on the wireframe, our graphic designers and mobile app designers created the look and feel of the mobile app that would be a charm to use for all the users.
Moving forward, once the designing is done, We moved to the development phase following the agile methodology framework. Potentially shippable products were delivered to the client every two weeks and the feedback was taken at every stage during the demo of the product. The development progress was transparent to the client and can be tracked on the project management tool JIRA.
