The cutover-window decision nobody makes early enough
Every S/4HANA migration has a cutover window — and the rollback decision inside it is the hardest call in the whole project, not technically but psychologically. The three questions the best teams answer before T-Day: the written go/no-go criteria, who holds the call, and where the point-of-no-return actually sits.
The S/4HANA deadline math most organizations calculate wrong
SAP ECC mainstream maintenance ends December 31, 2027 — but for most mid-market organizations the real cut-off was mid-2025, because transformation capacity is finite. The lead-time math, the capacity crunch, why procurement misreads ERP sourcing, the readiness signals that beat RAG status, the rollback decision nobody pre-commits, and why hypercare is where the program is actually judged.
