In a team meeting a decision is required about a proposed timeline change caused by a potential scope change. What should the project manager do?

The correct answer is to schedule a project decision meeting with all stakeholders to discuss the decision. This aligns with good project management practices, especially when a significant change like a timeline and scope alteration is involved. Engaging all relevant stakeholders ensures transparency, gathers diverse perspectives, and fosters buy-in, leading to a more robust and accepted decision. Following the stakeholder engagement plan is too general; the plan would likely recommend a meeting for such a critical decision. Reviewing the stakeholder map and delegating to the most senior person bypasses necessary discussion and collaboration, potentially leading to a suboptimal or unaccepted decision. Making the decision unilaterally on behalf of the organization is inappropriate for a significant change that impacts multiple stakeholders and could lead to resistance or rework.
