How industry dependent is this? Is this an artifact of the needs of a particular industry (aerospace, automotive) that has a lot of process to cover supplier quality concerns?
I've been in the ISP, MSP, Fed'Gov, and Manufacturing sectors in one way or another, and dealt with SAP in most/all of them. Some were worse than others about this, but it was a universal problem.
"CYA is SOP", hence millions of layers of approvals, QA, and change controls. Feddy'Gov was actually the fastest moving, in my experience, but they also didn't have to worry about manufacturing defects or breaking BGP nationwide.
