In a global project using a follow-the-sun approach, it is crucial to have effective communication to ensure a smooth handover of tasks and issues between teams in different time zones. Moving working windows to increase overlap allows for real-time communication and collaboration, which can help in addressing and resolving issues more efficiently. This approach aligns with the PMBOK guide's emphasis on effective communication management in projects1.

The project manager should review the team culture and the personality traits of the individual to address status update gaps. This will help to understand the root cause of the problem and find ways to improve the communication and collaboration within the team. The project manager should also foster a trusting and respectful environment where team members feel comfortable to share their challenges and feedback.
Creating a safe space for status updates, reviewing the team status updates more thoroughly, or supporting team inclusion and changing the format of status updates are all possible actions that the project manager can take after reviewing the team culture and the personality traits of the individual, but they are not the first action that the project manager should take to rectify this situation.

According to the Project Management Professional (PMP) principles, successful project outcomes are heavily dependent on adequate requirements gathering at the beginning of the project. If the villagers could not access water six months after the completion of the borehole project, it suggests that the project requirements may not have been adequately defined or understood. This could include understanding the villagers' needs, the environment, and the sustainability of the project solution. The Cost Performance Index (CPI) and Schedule Performance Index (SPI) indicate the project's performance against budget and schedule, but they do not necessarily reflect whether the project outcomes meet the needs of the end-users.

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.
