Business Needs:

Following were the requirements of the Partner –

  • This project is an Idea Based Development. Our partner, xWare42 GmbH had few ideas in his mind, which he discussed with us. Based on this, we started developing the project.
  • As it was an Idea Based Development, our partner wanted us to adopt Agile Software Development Methodology.
  • He also wanted us to upload each phase as soon as it is developed, which can be further viewed and analyzed by our partner and can also be amended, if required.
  • Our partner, wished to have an online platform. The product should function on the API (application programming interface) or the web services through our core banking system.
  • The product should provide support or be available to the end user all the time i.e. 24 x 7.
  • It should be process based and should be able to hold the interest of the end user. The basic out-look and further screens should have minimal fields to verify any user. Thus making UI (User Interface) more interactive and interesting.
  • The partner wanted to use the latest and cutting edge technologies in the project.
