When a team member starts missing deadlines, it is important for the project manager to understand the root cause of the issue. Meeting with the team member provides an opportunity to discuss any concerns or obstacles they may be facing, which could be affecting their performance. This approach is in line with the PMBOK guide's emphasis on project managers being proactive in identifying and resolving issues that can impact project timelines1. It also aligns with the principles of business analysis, which include understanding team dynamics and addressing individual team member's challenges to improve overall performance2.

The Professional in Business Analysis materials also stress the importance of understanding individual team member's needs and facilitating solutions to performance-related challenges2.
