The Full Form of CAMS is‍ Control and Monitoring.

According to the Project Management Body of Knowledge (PMBOK), “the Monitoring and Control Process Group consists of those processes performed to observe project execution so that potential problems can be identified in a timely manner and corrective action can be taken, when necessary, to control the execution of the project.”

Project Monitoring and Control activities take place in parallel with Project Execution Process Group activities so that, while the project work is being executed, the project is being monitored and controlled by implementing the appropriate level of oversight and corrective action.

The project is observed and measured regularly against the project plan to ensure that the project is within acceptable variances of cost, schedule and scope, and that risks and issues are continually monitored and corrected as needed.

The main purpose of monitoring and controlling activities is to be proactive in finding issues ahead of time and taking corrective action.  Corrective action can require revisiting Planning Process Group and updating the Project Management Plan as needed with the ultimate goal of bringing the project back in line with project objectives and constraints and improving future execution to avoid repeating the same issues.
