The Run phase of SAP Activate commences after the system has gone live and is in productive use. The measurement of actual user adoption metrics—such as transaction volumes, process cycle times, and user engagement analytics—can only be performed once users are actively working within the live production environment. This activity is fundamental to the Run phase's objective of monitoring, optimizing, and ensuring the solution delivers the intended business value. Earlier phases focus on planning for adoption and assessing readiness, not measuring actual usage.

A. Development of the user adoption strategy is a foundational planning activity that begins in the Prepare phase and is refined throughout the project.

B. Mapping of SAP roles to employees is a critical configuration and security task performed during the Realize and Deploy phases before go-live.

C. Conduction of a pulse check can be done in the Deploy phase to gauge user readiness before go-live, as well as in the Run phase for post-go-live feedback.

1. SAP Activate Roadmap Viewer for SAP S/4HANA Cloud Public Edition: In the Run phase, the workstream "Operations and Support" contains the deliverable "Continuous Adoption." A key task within this deliverable is "Monitor User Adoption," which explicitly involves measuring usage and performance to ensure the solution is being used effectively post-go-live. (Access via SAP Roadmap Viewer -> SAP S/4HANA Cloud Public Edition -> Run Phase -> Operations and Support).

2. SAP Activate Methodology Content: The official SAP Activate methodology documentation outlines that the Prepare phase includes the "Organizational Change Management Plan" deliverable, where the user adoption strategy is initially developed. This confirms that option A occurs much earlier than the Run phase.

3. SAP Activate for Cloud ERP Implementations (SAP Press, 2022): This official publication details the activities per phase. It places role-to-user mapping within the security and authorization tasks of the Realize and Deploy phases. It also describes readiness assessments (which can include pulse checks) as a key activity leading up to go-live in the Deploy phase, distinguishing them from the post-go-live monitoring activities of the Run phase.
