The IT department copes with a wrong system belief about IT, about the IT people and about the IT department.
Most non-IT people do not understand the IT department and IT.

The IT department must organise itself, for example define, learn and improve its processes, methodologies and methods.
It is hard to find really skilled people in IT.
The IT department must train its people. Its people should improve their skills.
The IT department has a bad reputation.
The IT department bears an enormous responsibility. Information systems cost a lot in building and in keeping them operational. A well designed information system can maximising its business value.
