After reviewing iteration deliverables with the customer, a newly joined key stakeholder says the results do not deliver the business capabilities expected. What should the project manager do to resolve this?

The correct answer is to conduct stakeholder identification and a project objectives review session. The newly joined stakeholder's unexpected feedback indicates a potential gap in understanding their needs or in communicating the project's objectives. Re-identifying stakeholders ensures all key players are known, and reviewing project objectives with them clarifies expectations and aligns understanding. This proactive approach addresses the root cause of the misalignment. Creating a change request and updating the scope management plan is premature without understanding the stakeholder's concerns. Updating the stakeholder list and fixing deliverables is reactive; fixing deliverables without understanding the underlying issue might lead to further problems. Updating the project management plan and lessons learned is also reactive and doesn't address the immediate need to understand and align stakeholder expectations.
