In software development the process is often called "Post Implementation Review" (PIR). This is also the time where auditors come in to review benefits realized. One intention is to improve the accuracy of future cost estimation processes.

Not sure whether this is done much in the age of rapidly changing technology and processes. I have not seen a proper review done at my workplace since the hectic days of Y2K work.
