Do you ever evaluate your department?
This is not about performance management, as that focusses mainly on individuals.
It's about evaluating the whole ICT support department and the level of support you offer to the school, how its delivered and how staff perceive you in the school with the aim to improve some or all of these, identify problem areas and be able to show improvement as some sort of figure(s) on a piece of paper (we all know head teachers love statistics!)
If you do, how do you do it? On-line surveys, E-mail surveys, questionnares, comments and suggestions box or any/all of the above? Or maybe something totally different. How often do you do it?
Or maybe you see this sort of thing as a pointless exercise that will just invite people to make pointless criticisms and achieve very little in the process.
Any input welcome! :D
