We can�t fully plan before we start, because we don�t know where we�re going � We can plan a little and continue to iterate the planning � When we execute, things will happen � Risk management is essential
� During the �control� phase, we need to measure what�s happening, so we have a chance of guiding the project � What do you measure, so you know where you are and can move to where you want to be? � If we knew when we were done, we�d close � So if we�re ready to release at a moment�s notice, we can close any time
