Don't forget the political. A lot of large corporate IT is outsourced to the likes of HP. It's not unknown for them to put in the least qualified folks they think they can get away with - which can often mean in the case of unusual infrastructure, libraries or languages that they sent someone on a basic training course the week before starting. This leads to the quality you might expect. The two most "interesting" contracts of my career were in financial. One was trying to reverse 25+ years of bad decisions and no end of duplicated, wrong, and unsanitised garbage in the live DB along with some dependency on CICS that fortunately I was far away from. The other will remain undiscussed. :)
