Case Study: a FTSE 100 energy and utilities company achieves a successful SAP S/4HANA transformation with Project One

a ftse 100 energy and utilities company goes live with Project One after a £100m SAP S/4HANA transformation

The customer, a FTSE 100 energy and utilities company, faced significant challenges in its multi-year program to migrate from a legacy SAP system to SAP S/4HANA. The initial release had not delivered anticipated improvements, causing stakeholder confidence issues and program delays, particularly as a more complex second release was underway. Project One was commissioned to perform an independent assurance review of the struggling transformation.

Project One conducted a review and then led a 10-week program reset. They embedded senior consultants in key roles for 18 months, including an IT Programme Director and leads for business change and user acceptance testing, to drive the implementation. The result was the successful go-live of the SAP S/4HANA solution after a three-year journey, transforming processes for several thousand users. The final program budget exceeded £100m and required careful cashflow management during a three-week outage. Project One provided the necessary expertise and senior-level experience to ensure the complex programme's delivery.
