A global industrial group inherited an S/4HANA Cloud implementation that was declared complete but couldn't be relied on, financial data didn't reconcile, month-end close didn't work, and confidence in the platform had gone. S5 stepped in as recovery partner, stabilised operations in under 20 weeks using the 5S delivery model, and moved the customer into a long-term AMS partnership. This is what S/4HANA recovery looks like when the goal is business trust, not more change.
