On April 9th, 2020, the GC Coordinated model & GC Digital Core template strategy was endorsed by GCEARB which included the following components:

  • Implementation of a “GC Coordinated Model” to enable the GC-wide transition to S/4 HANA and to deliver financial management transformation, utilizing a new operating and governance model.
  • Implementation of a “GC Digital Core” to support the transformation, which would have functionality built once, and used everywhere. This will accelerate implementations, avoid duplicative costs, and reduce the risk in transition to S/4 HANA.
  • Maximize technical architecture.
  • Maximize deployment options / clustering by reducing the number of SAP instances within the GC. This approach should significantly reduce the investments and the on-going operating costs, moving forward

In summary and in practical terms, the proposed strategy suggests that we:

  • In partnership with OGDs, standardize approximately 70% of our financial processes (paying a bill is paying a bill…) across the GC and let Departments “customize” 30% to meet their specific needs.
  • Encourage / enable the “clustering” concept across GC; preliminary assessments suggest going from 18 instances to 11.
