Your legacy system?
We discuss the right path with you
The right strategy

Brownfield or greenfield?

There are two main approaches. With the brownfield approach your existing SAP solution is migrated, which allows a step-by-step changeover. The greenfield approach means a complete new implementation. We help you decide.

Brownfield

System upgrade

Your existing SAP solution is migrated to S/4HANA.

  • Step-by-step changeover
  • Existing processes remain as the basis

Greenfield

New implementation

The legacy system is replaced and SAP is introduced completely anew.

  • Rethink processes
  • A clean start without legacy issues
Our migration process

In six steps to the new SAP world

With a structured approach we ensure a safe migration, transparent, plannable and efficient.

System analysis and strategy Inventory and selection of the migration method.
Data cleansing Optimize and prepare existing data structures.
Technical migration Transfer to the new SAP environment.
Test phase Ensure process stability and quality.
Go-live and training A start without interruption, users are trained.
Support and optimization Long-term support and continuous improvement.
Project approach

The HPC hybrid model: fixed framework, flexible delivery

The model combines classic and agile elements and builds on the SAP Activate model. At the start we capture requirements only roughly and refine them in small steps with interim acceptance. A visible work list (backlog) records what is implemented next. Your business side prioritizes it.

1

Discover

Analyze the situation, plan the strategy (greenfield, brownfield or hybrid) and roughly capture current processes.

2

Prepare

The project team starts: basic training, kick-off, prototype and first sprints.

3

Explore

Fit-gap analysis, capturing and prioritizing processes in detail.

4

Realize

Implement processes and requirements step by step, with interim acceptance.

5

Deploy

Cut-over, go-live and hypercare support.

6

Run

Regular operation with support and continuous improvement.

High customer involvement and short feedback loops: agile methods for a solution that fits closely, especially when goals and the paths to them still need to be refined.
