I'm describing the challenges that come with the governing implementation of a large number of SAP Fiori applications and the free tool that helps to ease those challenges called Fiori Tracker. Fiori Tracker serves as living documentation and a central registry of apps that are being implemented or supported in your S/4 HANA project. With Fiori Tracker whole team knows what apps are in scope and how they should be configured. It provides one view to manage the entire set Fiori apps. With Fiori Tracker the team gets one place to collect what was agreed with functional stream leads while enforcing naming conventions and avoiding duplication.
