Hi Alan

>Add an item [3] to that list. "Proper change control procedures". A large part of that 85-90% figure comes about because of changes introduced by those (usually in management) who 'sort of' bought into the project, but now figure they can introduce all the little bells and whistles to which they couldn't get agreement beforehand. Of course the project scope becomes wider without properly re-assessing budget and time estimates.

Ahhh! The dreaded "scope creep scenario". Yes this has killed more projects than I care to think about.
