A successful SAP S/4HANA implementation offers companies the opportunity to seamlessly integrate modern technologies such as IoT, Artificial Intelligence, and cloud-based solutions. While cloud technologies are becoming increasingly established, on-premises solutions remain relevant – but which approach is the right one?
The decision between a greenfield, brownfield, or hybrid approach is not just a matter of IT; it is a business decision that involves careful consideration of various factors. A thorough preliminary study will help you define the best strategy. Process governance, change management, and transparent communication are essential to ensure acceptance and efficiency right from the start.
But what is the optimal migration path?
The process of a preliminary study for an SAP S/4HANA transformation
A well-founded preliminary study helps to assess integration capability, system landscape, and risks at an early stage. Many companies opt for a step-by-step transition, in which individual organizational units or process clusters are migrated in a targeted manner. The essential question is: "How do we implement the strategy – and with what means?"
A structured preliminary study provides clarity regarding individual requirements and ensures a future-proof SAP S/4HANA transformation.
abat provides individual consulting support as part of a preliminary project (extended discovery phase according to SAP Activate, to identify the individual building blocks.
This is achieved by employing appropriate tools and methods, such as a value check or a system deep dive based on preconfigured state-of-the-art processes in the prototype system.
This approach enables you to substantiate your instincts. An SAP S/4HANA evaluation matrix is an effective tool for systematically recording the pros and cons of all stakeholders. In this environment, facts can be systematically compared and a reliable roadmap can be developed.
The abat S/4HANA Conversion Accelerator facilitates a streamlined and cost-effective transition to SAP S/4HANA. A thorough review of your current SAP system will allow us to determine the necessary steps for the conversion. We will then create a detailed implementation plan.

With abat AG, we were able to develop our S/4 roadmap in a short time with a clear picture of the next necessary steps as well as the opportunities with S/4HANA - despite working remotely, across several international locations, during the pandemic.
