What is the value of moving to SAP S4/HANA and how do I justify it to the business?
After spending many years getting an SAP ECC solution to the point that it meets the needs of the business, fully deployed and hopefully fully financed, how do I justify now moving to SAP S4/HANA?
At one end of the scale, SAP S4/HANA can be viewed as a necessary complex upgrade with the goal of re-implementing what already exists onto a new improved platform, making only the changes that are absolutely necessary for the existing solution to continue to work and continuing to use the GUI rather than introducing SAP Fiori except where it is the only choice.
At the other end of the scale, it may well be an opportunity to discard a solution that never quite realized expectations and wasn’t fully adopted by the business: SAP S4/HANA provides the ability to build a better process. Deciding where you are on this scale will impact your approach, cost and timeline.
The majority of A&D companies have changed significantly over the last twenty years through evolution, acquisition and divesture, and as a result, the SAP landscape that these companies have isn’t necessarily the one they would have chosen with hindsight. Moving to SAP S4/HANA provides opportunities not only to rationalize the SAP landscape but also to adopt common processes and provide a foundation for shared services.
The primary task for any business considering the move to SAP S4/HANA is to define the reasons for doing it, what opportunities they hope to realize and what challenges and obstacles are to be faced.
