I find it interesting that the current PMBOK dedicates 64 pages to risk management, and yet I cannot find the word “inhibitor” anywhere in the entire document. (Note: this is not a derogatory comment about the PMBOK).
It is my experience requiring resources to report inhibitor status on active tasks each working day, is a great source of information for the risk management plan. This information is active work performance data and can be included in work performance reports.
It is important to know if there is anything slowing the progress of a task, and it is better to know sooner than later.
