Here's a great question which was previously asked in our SAP Activate Community:
SAP provides lot of good BDCQ questions to prepare for fit-to-standard workshops (Business Driven Configuration Questions). Since sometime now SAP recommends Fit-to-standard for on-premise as well. My understanding is that we can reuse the BDCQ questions for S/4HANA Cloud for On-premise too and it is a very good starting point. BDCQ's are available in Roadmap Viewer (sap.com) under accelerators. Can anyone please confirm?
