It pays off to choose an SAP S/4HANA assessment

Many SAP customers need to consider ERP renewal as one of their biggest ICT investments over the next decade.

Jouko Juuti / June 30, 2023

We have learned from our customers that careful preparation work is an effective approach to obtaining management approval for transitioning to S/4HANA. Our S/4HANA assessment is a productized S, M and L sized offering to all customers.

Regardless of the customer's size, there are certain aspects that are common across all assessments. All the deliverables in our S/4HANA assessment are aimed at achieving tangible cost savings during the actual request for proposal (RFP) and project phases:​

  • The S/4HANA project will be efficient, as the majority of decisions are made during the assessment phase.
  • The future scope of the S/4HANA​ implementation will be well-defined and aligned with relevant business requirements.
  • You will get a comprehensive understanding of how to integrate or replace other systems as part of our assessment process.
  • Our assessment enables a better fit with the RFP, allowing implementation partners to provide accurate estimations without the need for risk margins in unclear areas.​

Based on the chosen S, M, or L package, the following deliverables are achieved through efficient workshops facilitated by professionals using readymade templates:

  1. Project plan for assessment
  2. Business requirements
  3. S/4HANA Business Impact Assessment
  4. The technical ability to implement S/4HANA through SAP readiness check, SCMON / UPL monitoring, custom code analyses and a technical view to required changes
  5. Future solution architecture including mandatory changes needed for achieving business requirements and business value impacts
  6. Process reviews and recommendations for changes: L1, L2, and L3 process documentation of the SAP use with S/4HANA
  7. RFP documentation for S/4HANA scope and requirements
  8. S/4HANA project implementation approach and roadmap (Greenfield, BLUEFIELD™ vs Brownfield) including data migration complexity views
  9. S/4HANA project governance model
  10. S/4HANA project cost estimate
  11. S/4HANA project qualitative business case, which showcases the value of SAP S/4HANA innovations​ for future strategic capabilities
  12. Final project report

One of our success stories last year was the SAP S/4HANA assessment carried out for Valio, a large dairy & food manufacturer and distribution company with wholesale operations in Finland, Sweden, USA, the Baltics and China.
