According to the PBA Guide, the project manager should facilitate the resolution of issues and conflicts that arise during the project, such as interruptions and requests for help from other teams1. This involves identifying the root causes of the problem, such as unclear roles and responsibilities, competing priorities, or lack of communication2. The project manager should then define the ground rules with all project team members to minimize interferences, such as setting boundaries for availability, delegating tasks, or using technology to avoid distractions34. This is also consistent with the PMBOK Guide, which states that the project manager should establish the team ground rules as part of the team development process5. By identifying the problem's root causes and defining the ground rules, the project manager can help the project team members avoid interruptions and requests for help from other teams, and focus on completing their tasks during the iterations.
