When a project is delayed due to a quality problem causing a large amount of rework, it's crucial for the project manager to take immediate action. The Change Control Board (CCB) is typically responsible for reviewing all change requests, including those related to project delays. The project manager should report the delay and the rectifying actions to the CCB for review. This allows the CCB to understand the situation, assess the impact, and make informed decisions on the next steps1. References:
