Responsibilities

Define and maintain a risk-based test approach across SAP implementation, rollout, migration, enhancement and transformation activities.

Enforce the test data strategy (synthetic versus masked production data, provisioning, refresh, privacy and compliance) and confirm data readiness per cycle.

Integrate non-functional testing into the cycle plan: performance, security and authorisation, failover, batch and throughput, usability.

Align with Business Process Owners, Engineering Leadership and SI/partners on scope, readiness and sign-off.
