The scenario describes the Plan Stakeholder Engagement process. Lessons learned repository is an organizational process asset which can be used as an input to this process. When planning stakeholder engagement for the project, the project manager should take in the lessons learned from other projects that had to engage with similar stakeholders. In the scenario, the project stakeholders of the senior management team are known not to respond or attend meetings. Other projects have learned ways to gather feedback or other forms of engagement. Learning from their successes and failures will reduce the chances of the current project repeating failures and increase successes. Planning approaches without consulting past or current attempts and methods risks the project wasting time, money, resources, and more. Details for Each Option: Patiently wait until management indicates that they are available to provide their input Incorrect. Passively waiting for stakeholders to determine their own engagement with the project is not a wise solution unless that approach is explicitly stated as a successful tactic from the lessons learned of other projects and conversations with the stakeholders. Schedule regular, short update meetings at a constant time and convenient location Incorrect. Senior management has a history of not attending meetings. Scheduling more of them and hoping for a different result is an unwise strategy. The type, timing, and structure must be understood first. Review lessons learned from other projects involving the management stakeholders Correct. Lessons learned from other projects can be an extremely valuable input to the Plan Stakeholder Engagement process. Learning from the successes and failures of other projects can guide the plans for the current project. Require one senior management representative to attend meetings or the project will be halted Incorrect. Forcing rules that a project manager may not be able to enforce is doomed to fail. A project manager's primary goal is to deliver project objectives within time and budget. Halting a project as a result of unattended meetings risks the goal being met.
