During a progress meeting, the CEO reported that a major stakeholder was unaware of recent project developments, even though the stakeholder was identified and classified in the stakeholder register. Which document should the project manager review to determine why this happened?

The Stakeholder Engagement Assessment Matrix helps determine if stakeholders are currently engaged as planned and identifies any gaps. It compares the current engagement level of stakeholders with their desired engagement level. In this scenario, the CEO's report indicates a gap in the stakeholder's awareness, suggesting their current engagement is lower than desired. Reviewing this matrix would reveal which stakeholders are not engaged as planned and help the project manager understand why. The Requirements traceability matrix links requirements to their origin and ensures they are met, but it doesn't track stakeholder engagement. The Issue log records problems that need resolution, but the lack of awareness is a symptom of poor engagement, not necessarily a new issue to be logged. The Stakeholder register lists stakeholders and their characteristics, but it doesn't assess their current or desired engagement levels.
