A Case Study in EAC Growth
EVM & Scheduling Track
The responsibility for the reporting of EACs is well established, and the methods for prediction, as well as the shortcomings in those methods are well known. This should result in good EACs and a good sense of the risk in those EACs. Occasionally, however, growth of apparently totally unexpected scope occurs. Why does this happen, with all of our experience and all of our processes? This paper will describe the growth of several EACs from the original prediction through several snapshots of what was known and what was reported. The motivations for the difference between what was known and what was reported will be discussed with a view towards understanding why these apparent surprises happen.
Behavior at several levels inside the organization will be discussed in an attempt to explain how there is sometimes what has been called “a conspiracy of hope.”
