According to the PBA Guide, the project manager should validate the stakeholder's understanding of the project management plan during the kick-off meeting, which is a formal meeting to communicate the start of the project and the expectations of the stakeholders1. This is also consistent with the PMBOK Guide, which states that the project manager should ensure that the project management plan is approved by the appropriate stakeholders and that the approval is based on a common understanding of the project scope, objectives, deliverables, and milestones2. By validating the stakeholder's understanding during the kick-off meeting, the project manager can prevent misunderstandings, conflicts, and delays that may arise later in the project due to different levels of understanding by international stakeholders.
