A customer found quality problems in recent deliverables, which the team fixed immediately. With the project back on track, what should the project manager do next?

The best next step is to perform lessons learned. While the immediate problem is resolved, a formal lessons learned process will identify the root cause of the quality issue, document what went wrong, and capture actions to prevent recurrence on this project and future projects. This proactive approach ensures continuous improvement. Reviewing the risk log is important for ongoing risk management, but it doesn't address the specific, already-occurred quality problem. Holding a team meeting to review the issue is part of a lessons learned process, but it's not the complete action. Continuing to monitor quality metrics is an ongoing activity, but it doesn't address the underlying cause of the recent failure.
