What is a Control Plan?

The Control Plan is a guide to continued monitoring of the process, and the response plan for each of the measures being monitored. These three elements have been initiated earlier in the process, but in the Control phase, the monitoring is reduced to key input, process and output measures that will provide critical leading and lagging indicators during the project tracking period after implementation.
