This article is bang on the money and I see these problems everyday. Change management, while well intentioned, can be built around ill conceived processes and go completely out of control, to the point where change is virtually impossible. The parallels between the signoff process you describe and the signof process at my current employer is uncanny. So, as well as stopping people changing things for the worse, these processes additionally stop people being able to change things for the better! At this point, almost invariably, people decide that if they're not permitted by change management to do the job properly to a timescale that's acceptable they'll have to fudge something else in under the radar. Cue another spreadsheet based approach, which nobody will know about, nobody will formally support and nobody will even understand once the trader who cobbled it together leaves the desk.
