The document provides guidance for developers preparing to implement SAP S/4HANA. It recommends: (1) planning the project in iterative cycles using sandboxes to capture issues early; (2) including end users in workshops from the earliest stages; and (3) embracing new development paradigms like ABAP Test Cockpit and unit testing. Developers should also get up to speed on enabling Fiori apps and services, core data services, and new UI options in S/4HANA. Following bloggers can help with preparation.
