This document discusses the journey to improving user experience (UX) with SAP systems. It notes that the journey has no clear destination and there are many paths, and the journey is never complete. It recommends starting with some easy initial improvements like wrapping the SAP GUI in the NetWeaver Business Client and then experimenting with technologies like screen personas, side panels, and Fiori apps on mobile/browser. The document advises planning improvements incrementally but not too far in advance, making strategic choices about mobile technologies based on factors like audience and backend systems, and pursuing a hybrid web frontend strategy to combine the best of native and web apps.
