I was at a defense contractor early in my career, and the government had this idea that our CMMI-certified process was supposed to demonstrate that defects were being found and corrected at various stages of the review and testing process.

Implicit in this was an assumption that a certain number of defects were there to be found in the first place. As a result, if you were too thorough and conscientious before your reviews it actually reflected badly on your reviewers, because they weren't finding anything. As a result, we started pushing out intermediate WIP that we knew had problems so the defects could be "found" and "fixed".
