For over ten years now, Stadtwerke Dinslaken has trusted Arvato Systems as its SAP partner for the operation and support of its systems. In the now-completed major project, the commercial core system was successfully converted to SAP S/4HANA as part of a greenfield implementation. From the preliminary study to agile sprints and productive implementation, Arvato Systems accompanied the customer through all phases of the project, achieving proven success.

Project Overview

Initial situation

Stadtwerke Dinslaken chose Arvato Systems as its service partner for the operation and support of its integrated SAP ERP and SAP IS-U landscape. Based on a preliminary study, Stadtwerke Dinslaken decided to decouple the commercial core system from SAP IS-U and transfer it to a modern SAP S/4HANA system.

Vision

The goal was a complete greenfield approach with SAP best practices based on SAP S/4HANA. The new system landscape needed to be modern, flexible and future-proof - with clear responsibilities between the core system and the industry solution.

Solution

On the basis of the SAP Activate method model and an agile approach, 116 user stories were defined in close coordination with the specialist departments. The implementation was carried out in five sprints. After intensive Testing with about 600 test cases the system was successfully introduced - including stable Hypercare-Phase and handover to the AMS team.

Advantages

Quick project start thanks to SAP best practices

Thanks to the use of preconfigured systems, the project could be started quickly - without a time-consuming preparation phase.

Agile implementation with complete transparency for specialist departments

Iterative development in sprints enabled the specialist departments to see the solution at an early stage, provide feedback and thus actively help shape the target architecture.

Reduced migration effort thanks to preconfigured content

The use of the SAP migration cockpit with prepared templates minimized manual effort and noticeably accelerated the data transfer.

Stable GoLive after intensive test phase

Comprehensive test cycles and a structured Cutoverplan ensured that the GoLive and the Hypercare phase went according to plan.

Successful implementation despite project delay

Despite a necessary extension of the implementation phase, the project goal was achieved on schedule. After intensive testing, a stable system status was established and transferred to regular operation.
