According to the PMBOK Guide, 7th edition, project governance is the oversight function that aligns the project with the organization's governance model and encompasses the project life cycle. Project governance provides a framework for making decisions, resolving issues, and escalating risks among the project stakeholders. When a project is facing delays due to conflicting views between senior management and external stakeholders, the project manager should review the adequacy of the project's governance and ensure that an appropriate structure is in place to facilitate effective communication, collaboration, and decision making. The project manager should also consult the project charter, the stakeholder engagement plan, and the project management plan to identify the roles, responsibilities, and authority levels of the project stakeholders and the escalation process for resolving issues. The other options are incorrect because they do not address the root cause of the problem, which is the lack of clear and consistent project governance.
