SAP S/4HANA in focus

Shape your digital future with BDF EXPERTS

"Converting to SAP S/4HANA offers the opportunity to scrutinise existing business processes, standardise them and optimise them. Don't let this potential go unutilised during a changeover. Whether SAP Greenfield, SAP Brownfiled or BDF Colouredfield - we will be happy to advise you!"

Your way to SAP S/4HANA

With SAP S/4HANA, you can create the basis for a digital company. However, it is important to bear in mind from the outset that a changeover is not just an IT project, but above all a transformation project that affects the entire company. Therefore, involve all stakeholders at an early stage and take a holistic view of processes. BDF EXPERTS will be happy to support you in this with

  • Proven best practices from various industries
  • An efficient project methodology
  • A structured roadmap for your implementation
  • A unique approach to the changeover

Discover your strategy

Every company has its own IT landscapes, established processes and individual requirements. The path to SAP S/4 HANA must therefore be analysed and mapped individually for each customer. At the BDF compact workshop Discovery, we discover your possible path to SAP S/4HANA and consider together which steps make sense until then.

Comparison of implementation approaches

SAP distinguishes between two approaches for the implementation of S/4HANA. The SAP Greenfield and the SAP Brownfield approach. Greenfield involves a completely new implementation, while brownfield involves the technical migration of the existing system. BDF EXPERTS has developed another approach: The Colouredfield approach. It combines the best of the SAP Greenfield and SAP Brownfield approaches and brings efficiency gains from the very first investment.


The ERP system is being completely rethought from an S/4HANA perspective. Processes are redefined and implemented. The data from the old system must be painstakingly transformed into the new system. A greenfield project usually has a very long project duration due to the redefinition of the processes and the complex data transformation and requires higher investments than a project that is carried out using the BDF EXPERTS approach. Old process knowledge is lost and the efficiency gain only starts after the new system goes live.


With the brownfield approach, the old system is migrated to the new S/4HANA system. This is a 1:1 transformation of the database tables. The possibilities and opportunities offered by SAP S/4HANA are not utilised because the processes remain the same as before. As a result, it is likely that the efficiency of the processes will actually decrease after a changeover to S/4HANA because the requirements of the new system are not 100 per cent fulfilled.

Colouredfield approach

The Colouredfield approach combines the best of the Greenfield and Brownfield approaches. First, process optimisation is carried out on the old system with regard to the new possibilities under SAP S/4HANA. By taking up the old processes, process knowledge is not lost but continues to be utilised. Thanks to the step-by-step optimisation, you will already notice initial successes such as greater process efficiency or reduced time expenditure during the project term. Technical data migration takes place flexibly at any time after all your processes have been optimised.

Advantages of the coloured field approach

Once the process optimisation has been completed, you are ready for the changeover to SAP S/4HANA at any time, but can also continue to work with ECC.

Even after process optimisation, you benefit from faster and less complex processes. This saves you time and money.

Our processes are not designed on the drawing board, but have been tried and tested in practice. Our best practices are based on the experience gained from numerous projects in various industries under both SAP ECC and S/4HANA.

"Process expertise is our key to successful implementation projects. We have also been a leader in the SAP S/4HANA environment since the first release. We take away the fear of a changeover by showing you the potential of S/4 HANA projects and never leaving you alone on the path to success."
