Be wary the out of scope feature pile. Sure it is a quick and easy way to kill off an entire new project’s worth of work, but did you kill it the right way? Make sure that when moving requirements to an out of scope status that the reasons for the decision are recorded and who made those decisions.
The best case will be where the feature has been mapped against a business objective that will not contribute enough to the organization’s end goals. Can’t argue when someone’s favicon didn’t make the cut since it would provide an estimated 2 cents to the yearly income from bookmark recognition.
The worst case will be a project’s funder coming to you asking why his requested feature to save sales proposals in the system didn’t make the cut while you stare blankly at your documentation looking for anything.
