Overall good points but don't forget that pre-approval processes resulted in asking for resources that exceeded the near term needs and once approved ongoing costs were rarely fully reviewed. I have personal experience with "enterprise" clients making a huge months long process to get server resources, reminding us that changes would take 30+ days. when the project was over and we did everything we could to let them know that the servers could be spun down or put to other uses we got back a "ok thanks!" only to find them still running our project code YEARS later. This is infra that was costing them about 1 engineer FTE per year, not even a 10$/mo toy env
