A key project team member computes about being left out of the communication loop, in order to ensure that each key member is involved, who should review management plan?

Limiting the review to just the business analyst overlooks the vital contributions of the project manager and stakeholders. While the business analyst has critical knowledge of the project requirements, the project manager's oversight and the stakeholders' insights are equally important for a thorough understanding of the management plan. This narrow focus could lead to gaps in communication and understanding.

Excluding stakeholders from the review process is a significant oversight. While the business analyst and project manager are key team members, stakeholders have a vested interest and can provide essential feedback that might be critical for the project's success. Their absence could hinder effective communication and alignment with stakeholders' expectations.

While this option includes the project manager and the sponsor, it omits other key stakeholders who might have valuable insights into the management plan. The sponsor's role is important, but excluding other stakeholders could result in missing important perspectives that affect project execution and acceptance.
