Your Transformation to S/4HANA
Depending on what S/4HANA deployment option you decide on, there are two options to approach transformation: the Greenfield approach, which is starting from scratch, or upgrading SAP ECC 6.0 in a Brownfield approach, which allows the transformation without re-implementation and without disrupting existing business processes.
The combined approach - a hybrid one - enables you to choose the best parts of Greenfield and Brownfield approaches for your implementation roadmap. This approach is best for large enterprises with a complex ERP-Landscape (several SAP & legacy ERP) and large data volume.
Below you can find a short introduction to all three S/4HANA transformation approaches
Greenfield
New Implementation
If a company decides to adopt the Greenfield approach, it abandons its existing ERP system. This has the advantage that a new, uniform system can be implemented that only contains the processes and data that are actually necessary.
If a company completely redefines its enterprise architecture, innovations can also be integrated more easily and a high level of functionality can be achieved. In the study mentioned above, only 14 percent of all respondents chose this approach because it involves more effort.
When transitioning to the SAP S/4HANA cloud version, the Greenfield approach is the only valid approach since the systems are completely replaced by a new SAP cloud solution / tenant.
Brownfield
System-Conversion
With the Brownfield approach, a system conversion takes place. This means that existing business processes are taken over and optimized if necessary.
Since most companies do not want to completely abandon their custom ERP system, the Brownfield approach is the most popular migration path. According to the study, 44 percent of respondents choose this strategy, while 42 percent opt for a combined Greenfield and Brownfield variant.
To ensure a smooth transition, EA tools are used to divide the conversion into clear phases. The tools also ensure that old processes are rethought so that redundancies and complexity are not adopted. The advantage over the Greenfield approach is that the project time for system conversion is reduced.
Hybrid
selective Data Migration
The hybrid approach and its landscape transformation is not an independent transformation strategy. It is simply a method that large companies with complex system landscapes can use to prepare for transformation. In practice, this means that databases are cleaned up and consolidated to reduce the Footprint before the change.
Companies can also use this approach to combine several ERP systems from different vendors. Such a simplification is also possible during the actual transformation. Whether this makes sense depends on the system landscape and the target system. In many cases, an enterprise architect works with all three approaches to achieve the best possible approach.
This approach gives the option to accelerate your move to S/4HANA with a Finance First Approach with the fast adoption of S/4HANA Finance Innovations or in case of large multi-ERP Landscapes with SAP Central Finance CFIN..
