SAP S/4HANA Transformation

SAP Hero

SAP S/4HANA transformation is a critical piece of an enterprise’s broader business and technology strategy. It’s a key aspect of digital transformation journeys yet also one of the biggest challenges within the SAP environment.
Due to the complexity and the high level integration of SAP environments, the key success factors for a successful S/4 journey are transparency of current SAP and non-SAP landscape and proper milestone planning.

Build effective architectural roadmaps to accelerate S/4HANA transformation

Explore As-Is architecture and classify business capabilities

  • Identify and classify the business capabilities into areas of innovation and differentiation using Gartner’s Pace-layering method
  • Identify and partner with relevant stakeholders across business to effectively manage change throughout the transformation
  • Identify which parts of the As-Is IT architecture will be affected by S/4 transformation
  • Make use of integration capabilities to increase data quality and reduce manual efforts of maintaining IT components

Model and compare migration scenarios

  • Build a project discovery team and model scenarios based on As-Is and To-Be landscape e.g. Greenfield (New Implementation), Brownfield (System Conversion) or Selective Data Transition
  • Define the impacts of scenarios on the current IT and business architecture (e.g., applications, processes, business interfaces)
  • Visualize target S/4 architecture for each scenario at various points in time and compare it with current legacy SAP architecture
  • Use Free Draw capabilities to model different architectures (For eg., one global S/4 or multiple systems divided by region or business unit)

Use data to decide the right migration strategy

  • Identify dependencies between applications in IT landscape
  • Make Master Data Management a collective IT priority to avoid data leakage or loss during the transformation
  • Use data flow diagrams to gain complete overview of the interface (even outside the SAP environment)
  • Analyze integration architecture while focusing on select parts of SAP landscape

Leverage Signavio integration for process mapping

  • Identify the processes associated with business capabilities being improved/enhanced
  • Review processes using the Signavio (SAP) Integration and decide if they should be kept or redesigned
  • Use the seamless integration with Signavio to redesign and optimize processes
  • Leverage the transparency of IT and process landscape to plan budgets and resources accordingly

Create an execution roadmap

  • Create a transformation roadmap based on the chosen migration strategy and easily identify dependencies or conflicts
  • Communicate project milestones for main and sub-projects (e.g., roll-out plan, start dates, testing & validation timelines, test cut-overs, and go lives)
  • Track transformation progress to measure stages of completion and cost savings
  • Keep EA documentation up-to-date and automatically execute impacts after the completion of a project or plan
