The fun part of bank bureaucracy is you get to experience it 10x worse if you actually work at one.

I once worked on a global, cross-asset application. The change management process was not designed for this and essentially required like 9 Managing Directors to click "approve release" in a 48 hour window for us to do a release.

We got one shot at this per week, and failing any clicks we would have to try again the next week. The electronic form itself to trigger the process took 1-2 hours to fill out and we had 3 guys on the team who were really good at it (it took everyone else 2x as long).

Inevitably this had at least 3 very stupid outcomes -

First we had tons of delayed releases. Second the majority of releases became "emergency releases" in which we were able to forego the majority of process and just.. file the paperwork in retrospect.

Finally, we instructed staff in each region to literally go stand in the required MD delegates office (of course the MD wouldn't actually click) until they clicked. The conversations usually went something like this "I don't know what this is / fine fine you aren't gonna leave, I'll approve it if you say it won't break anything / ok don't screw up"
