Transition to SAP S/4HANA

Many companies want to align themselves and their processes with the future and are already thinking about switching to SAP S/4HANA.

How can a changeover be approached? Which strategy makes the most sense for your company? Are you also considering this transition as an opportunity to completely redefine your company's processes or whether you would prefer to adopt the established processes? Would you like to keep the constantly optimized programs and modifications to the system or would it be better to return to the SAP standard?

How can quick success in the changeover achieve an increase in acceptance? And what is better: a change project with a high proportion of IT or an IT project with a high proportion of change?

In short, which path should you take? Brownfield, Greenfield - maybe better a hybrid approach - coupled with Big Bang or rather phased by location, business unit or per process?

The strategy determines the success or failure of a transition to S/4HANA and the associated change in your IT.

The switch to S/4HANA is much more than just an upgrade to a new version. With S/4HANA, SAP shows simplifications in many places. First, a number of prerequisites must be met in order to take advantage of digitized business processes and technologies such as big data, real-time analytics, cloud computing, and mobile applications.

A switch in the brownfield approach is tempting and enables the integrated adoption of data, customer-specific developments, established processes and thus the preservation of competitive advantages. On the other hand, there is the possibility to carry out further optimizations as well as streamlining in the greenfield approach. This implementation approach strengthens change management and offers the opportunity to harmonize and standardize processes.

SAP S/4HANA migration is therefore not only a technical challenge, because processes in almost all business areas are often affected.

Another possibility is the combination of brownfield and greenfield, i.e., the transfer of individual modules from the existing SAP landscape to a newly built environment. Unfortunately, there is no silver bullet. A customized solution is needed for your company that does not overburden your organization and ensures business operations during the transition phase. That is why the question of the right strategy plays a central role here. After all, motivation and goals always differ from company to company.

In this way, you take the right approach together with us and create a successful transition.

We support you on your way to S/4HANA - with our process model for sound decision-making. Using our field-proven knowledge, we work with you to create an evaluation matrix according to your individual preferences. In this way, we pave the way for the successful introduction of S/4HANA in a brownfield, greenfield or hybrid approach.

To help you decide which path to take, we support you in recording your current situation and your system landscape, defining goals and milestones, developing an implementation strategy, evaluating the effort required depending on the variant, and selecting a changeover scenario that is optimal for you. We then transfer everything into a project plan with all relevant steps. Likewise, we identify activities that you can carry out in advance.

In other words: What are the details of the transition, what should you start with, and what activities can be started before the transition to minimize project risk? For the selection of the right approach and successful implementation, take advantage of the experience we have gained through many projects in medium-sized companies and corporate environments.
