The thesis work has been conducted with the collaboration of NEXI Digital S.R.L., inside a team adopting the SAFe framework for Agile development methodology, which is a methodology used in large organizations with multiple teams cooperating among themselves, to develop complex products in a very quick and continuous way, using a specific set of technologies. The case study is about the MyPayments application, which manages merchants’ data and different kinds of PoS implementations. This application is in the digital payments market and allows to manage physical PoS terminals, but also soft PoS terminals, which are increasing over time also because they work on common smartphones.
