Stay inside the IT framework, no matter how dysfunctional it is.
I did this in 1999, told my new boss to just get me a spare PC and I could handle the morning report printout ourselves. Want a change? Done in minutes, not months. Those web postings? Simple, couple lines of VBA to FTP. Another report? Sure. The Access database can manage all those mapping locally outside of Oracle. Corporate goal calculations? Err, why not. Daily compliance reports? Ok... Just give me admin on a SQL Server and I'll manage the tables...
Then it broke on vacation, so I had to modem in from FL. I became tied to this beast as the sole programmer supporting a dept of 8 people. I never got a budget for hardware upgrades, never got awards or credit for project management, since this thing was off the books. It took 7 FTEs to rewrite the mess after personal life & management changes in 2009.
In retrospect, I should have let IT do it and played the beurocracy. It would have made me happier in the long run.
