As an example for inappropriate use of resources. At a previous job, the IT manager was also responsible for changing light-bulbs and putting in new plumbing when we took over the office's ground floor, (e.g. putting in new radiators).

The department was only about 5 people, (the company was about 150 in total), but that was seriously part of his remit; technically it was IT's responsibility, but he decided that he didn't want the two support people and two developers having to do that.
