The project manager should discuss the issue with the team members at fault and find out the root cause of why they did not fill out the status reports. The project manager should also remind them of the importance and urgency of the status reports for the project sponsor and the project success. The project manager should also work with the team members to establish a clear and consistent process for reporting the project status and ensure that they follow it. Reprimanding the team members, justifying their behavior, or quickly putting together a report are not effective ways to address the situation, as they may create resentment, mistrust, or inaccurate information. References:
