Pressure to act is rising: Maintenance of the SAP R/3 system officially expires in 2027 – SAP S/4HANA is on its way! For medium-sized companies, this means that they will be forced to deal intensively with a project of supreme complexity and the risks associated with this. Fear of failure is great and justified in German SMEs. Even large and experienced companies regularly overestimate themselves in the implementation of such projects.

Many non-trivial questions need to be answered before the actual start of the project:

  • What are the benefits of converting my ERP system?
  • What will the conversion cost me?
  • What are the biggest opportunities and risks?
  • Is there a correct way to set up my project organization?
  • What is the difference between R/3 and S/4HANA?
  • What is the advantage of greenfield and brownfield approaches?

Finding the right answers to these questions points the way forward for the project and puts companies – especially small and medium-sized enterprises – in a position to face their first challenges right from the start.

Many consulting projects have shown that our clients repeatedly commit almost identical implementation errors. In some cases, these mistakes inevitably lead to a loss of balance within the project and thus to the project goals being missed. We have summarized the 10 biggest implementation errors in our impulse “Conversion to SAP S/4HANA”.

As well as a large number of risks, S/4HANA conversion projects also offer companies great opportunities. For example, errors or omissions from the conversion to SAP R/3 can finally be addressed. Business processes can be largely revised, harmonized and integrated before being mapped in the new system. The quality and use of data can be significantly optimized, thus creating an essential prerequisite for the far-reaching digitalization of process chains. In summary, you will have the rare opportunity to significantly and sustainably increase the performance of the entire company, thus secure, and even expand the competitiveness of your company in the long term.
