The Periodic tracking (for example, daily, weekly, monthly, quarterly, annually) of any activity’s progress by systematically gathering and analyzing data and information is called Monitoring.
In P3® program monitoring provides a holistic view of the program and status of each component of the program as well. The consolidated view of the program helps program managers view the program’s current status at any point in time. Program managers can also view status of each of the program component, projects individually to see the progress of individual projects within a program.
