Vital Statistics

This view tends to lose sight of vital information. In general, when only the work product is preserved, we know what we got in the end but not how we got it. How the software was generated, the decisions along the way, are essential parts of the process. Do we want to trust to memory? Do we care only about our mistakes or do we also want to learn from them?

A particular problem with groups that keep only the end product of software development is that they do not preserve a record of what they didn't do. Often it can be as important to know what approaches were rejected and for what reasons as to know which were selected. This is vital information to have when it comes to future versions or systems or to preserve for when the current system goes down the tubes.
