Independent health check of your S/4HANA go-live outcomes — evaluating configuration integrity, data migration quality, integration health, access governance, and whether the original business case has actually been realised.
Most S/4HANA programs go live under pressure — and that pressure leaves residue. Configuration decisions get made in the final sprint that never get revisited. Data migration gaps get logged as post-go-live defects and stay open for months. Integration failures get monitored manually. Role designs that were accepted in UAT carry SoD conflicts into production.
An independent post-implementation review — conducted 6 to 18 months after go-live — gives program sponsors, ERP platform owners, and internal audit a clear, objective picture of where the program landed versus where it was meant to land.
6–18 months post go-live
Typical engagement window
2–3 weeks fixed scope
Duration
5 structured deliverables
Output
Review of key configuration decisions made under go-live pressure — custom code, user exits, BAdI implementations, open authorisation objects, and table-level access still exposed in production.
Assessment of RFC connections, IDoc failure rates, PI/PO or Integration Suite middleware reliability, API Management gateway coverage, and unmonitored interface gaps.
Completeness and accuracy review of migrated master and transactional data against cutover sign-off records — identifying legacy data gaps, reconciliation failures, and ongoing data quality issues.
Review of role design decisions, segregation of duties conflicts introduced at go-live, Fiori tile access gaps, and GRC Access Control rule exceptions that were never remediated.
Assessment of whether the original business case KPIs — process cycle time reductions, headcount efficiencies, reporting improvements — have been measured and achieved post go-live.
Review of the hypercare-to-BAU transition, support team capability gaps, monitoring coverage, run-book quality, and outstanding defects still managed outside the system.
