@Lurk: that sounds like an awful place to work!

If your managers have to understand and work with anything that doesn’t fit neatly into a narrow area, surely that must get frustrating, boring and demoralizing for anyone with any sort of ideas or initiative.

I work in a very large organization and 98% of the day to day work, including huge initiatives, happen between the people who are (drum roll) doing the work, no matter the org chart.
