The best course of action when there is a misalignment of understanding regarding the project scope between the project sponsor and the project team is to facilitate a stakeholder alignment session. This approach is supported by the PMBOK's emphasis on the importance of stakeholder engagement and communication to ensure a shared understanding of the project's objectives and deliverables12. It is also in line with the PMI- PBA's focus on ensuring that all stakeholders have a common understanding of the project scope and objectives, which is crucial for successful project outcomes34.
