The implementation project initially began with an intensive phase of end-to-end process design. “We first defined, discussed and documented all conceivable processes in joint workshops,” explains Fabian Wick. “I should also mention here the ideal process flow, which we call ‘happy flow’ and which we defined alongside numerous exceptions to the standard.”
The processes were initially documented in Excel and then transferred to the open-source tool draw.io. With the aid of the software, the consultants created process flow charts that were used, among other things, for training the project participants.
The project team also used the defined and documented processes as the basis for mapping with SAP Best Practices. “Our approach was clear: rather than building the system in line with the processes, we would build the processes in line with the standard,” explains Fabian Wick. All change requests for non-standard solutions had to be specifically reviewed by the Board of Heliatek as ‘guardians of the standard’.
The team thus developed a suitable target system with SAP S/4HANA as its digital core, defined and designed the target processes, and completed the implementation. “The go-live at the start of February 2022 went well, mainly because of the excellent preparation.” We now have to wait and see if the system continues to prove itself when we ramp up production. However, we are very happy, and the first signs are that the implementation has been a success,” says Thomas Martin.
