A new project manager finds roadblocks during execution. Processes match a previous troubled project, tasks are behind schedule, yet the team is following processes exactly. What should the project manager do?

The best course of action is to review and amend processes. The problem states that the team is following processes exactly, yet the project is behind schedule and experiencing roadblocks, similar to a previous troubled project. This suggests the processes themselves are inefficient or contain non-value-adding activities, leading to delays despite adherence. Optimizing processes will address the root cause. Reassessing resource assignments might help, but if the processes are flawed, even optimal resource allocation won't prevent delays. Revising the schedule and updating the variation register are reactive measures that acknowledge the problem without addressing its underlying cause.
