Overwhelming Bureaucracy in the IT Department?

Nedry57 asks: "I am in the somewhat unique position of being a technology worker, who lives outside of the IT department in my company (a very large organization in the US). By far, the biggest challenge I face is getting anything done due to the bureaucracy that exists, within IT. There are certain tasks (i.e. anything that happens in the data centers) that I don't have the access to do. Even a simple task, like installing more memory in a non-production server, can take nine months and massive mountains of paperwork (no exaggeration), thus costing many times more than it should. The lack of agility is maddening, because I know we are missing significant business opportunities. My management is extremely supportive and despite our excellent track record of success in creating robust/secure applications--our work has passed audit numerous times with flying colors--we get no support from IT. Even senior management can't break through the barrier. I am very interested in hearing the experiences Slashdot readers have had in similar situations." How do you get your technology work done, when your IT department is more hindrance than help?
