Midway through a three-year contract, a political change replaces 20% of stakeholders, causing decision delays, unpaid invoices, and chaotic meetings. Which tool would help the project manager better understand the new project landscape?

Stakeholder analysis is the correct choice because it systematically identifies all stakeholders, assesses their interests, influence, and potential impact on the project, and determines appropriate engagement strategies. Given the significant change in 20% of stakeholders and the resulting issues (decision delays, unpaid invoices, chaotic meetings), a new stakeholder analysis is crucial to understand the new landscape and adapt engagement. Communication analysis focuses on communication methods, not the stakeholders themselves. Power distance analysis is a cultural dimension, not a project management tool for identifying and understanding stakeholders. Engagement analysis evaluates the effectiveness of current engagement, but a new stakeholder analysis is needed first to define who needs to be engaged and how.
