According to the Project Management Professional (PMP) Reference Materials, the project manager should perform a stakeholder evaluation in order to realign the project with the sponsor's expectations. A stakeholder evaluation is a process of identifying and analyzing the needs, interests, expectations, and influence of the project stakeholders, especially the key ones such as the project sponsor1. By performing a stakeholder evaluation, the project manager can understand the root cause of the sponsor's dissatisfaction, communicate effectively with the sponsor, and address any gaps or issues in the project requirements2. The project manager can also use various tools and techniques, such as interviews, surveys, focus groups, and stakeholder analysis matrices, to gather and document the stakeholder information3. The other options, A, C, and D, are not the best actions that the project manager should take to realign the project with the sponsor's expectations.
Reviewing the project goal diagram with the team may not help to resolve the sponsor's concerns, and may not reflect the current state of the project requirements. Confirming which templates the team should be using may not improve the quality or clarity of the project requirements, and may not address the sponsor's needs or expectations. Reviewing the risk management plan may not be relevant or helpful for the project requirements development, and may not involve the sponsor's feedback or input.
