Phase 0 is the strategic preparation stage that establishes clarity, alignment, and readiness before committing resources to an SAP transformation. This work determines whether the implementation should start at all, and if so, how.

Six months into an SAP S/4HANA migration, your enterprise architect asks a straightforward question: “Where’s the data mapping specification for customer master records?” Nobody knows.

The software keeps getting better. The tools keep getting better.  Implementation Methods and consulting approaches keep getting better. Yet, the failure
