The objective of the Controlling a Stage process is to ensure that:
PRINCE2® 2009 describes project monitoring within the Progress theme.
The purpose of the Progress theme is to establish mechanisms to monitor and compare actual achievements against those planned;
provide a forecast for the project objectives and the project’s continued viability; and control any unacceptable deviations.
Two of the principles of PRINCE2 are managing by stages and continued business justification.
The Progress theme provides the mechanisms for monitoring and control, enabling the critical assessment of ongoing viability.
