You know how management hates (surprises) having to do with cost or schedule overruns. Normally, a cost or even a schedule variance of let's say, 5% to 10% may not be an immediate project problem. However, a recently discovered or reported variance of 100% in a particular project phase and, in the middle of a project, is cause for immediate action! What action would you have taken, and in what part of the planning cycle, to perhaps, prevent or at least, minimize such a (surprise)? Please be prepared to defend your response.
