It was fairly early in my career in IT that I realised that very few other people at the company really understood what it was that I did, or at least that, as long as the outcome was 'good enough' then how I got there didn't matter and no company has the time to have people monitoring _how_ anyone is doing their jobs (outside of where such things are heavily regulated or prevent fatal accidents kind of things).

It's liberating. There seems to be more scope for freedom in what you do than most people think there is.
