I've seen this arise from financial policies whereby the IT cost centre must be financially self supporting. Hence IT department has to charge everything it does, swamping everyone involved - business and IT both - in bullshit paperwork, taking time from everyone. Like a finance version of fighting entropy, you can have everything perfectly neatly ordered but it takes effort. Then someone in IT gets sick of hearing bullshit hopes and dreams ideas from business; "Ok, but what if cereal box toys were spruced up with crypto? Go cost it up will ya?" And so IT swings the financial ban hammer with $20000 quotes. Bullshit begets bullshit. There will be a "who you know" club of people from business and IT who can skip the bullshit, not fill out the financial paperwork, meet over coffee or lunch and hash out ideas. If this club does not exist, woe betide the company.
