Some of your Stakeholders reported to you that they are not receiving status reports and other regular information on the Portfolio progress. This has caused a big issue with the governance board…

Since the stakeholder analysis is complete and the communication matrix is already defined, the failure to deliver reports points to a technical or configuration issue in the Project Management Information System (PMIS). Correctly configuring the PMIS ensures that the distribution of information follows the approved communication plan and matrix. This is the most targeted and efficient resolution to a delivery failure without revisiting planning documents that are already complete.

Re-analyzing individual stakeholders is unnecessary because the analysis is already done; the problem is delivery, not planning.

Updating the Communication Management Plan is not needed since the plan is presumably correct - the issue is that information is not being distributed as planned.

Updating the communication matrix is not required because the matrix already defines who should receive what; the delivery system is the problem.
