Explanation
According to the PMBOK Guide, 7th edition, one of the key practices for stakeholder engagement is to
"engage stakeholders to understand their needs, expectations, and interests, and to obtain their support and commitment for the project" (p. 121). This practice involves identifying and analyzing stakeholders, developing and implementing stakeholder engagement plans, and monitoring and adjusting stakeholder engagement activities. The project manager should allocate time to gain buy-in from the stakeholder prior to key decision meetings, as this will help to reduce resistance, increase collaboration, and enhance the quality of decisions. Updating the project schedule, asking that only key decision makers attend the meetings, or updating the risk register are not effective ways to handle the situation, as they do not address the root cause of the problem, which is the stakeholder's lack of alignment with the project objectives and approach.
