All (or nearly all) service management problems are People problems.
Sounds to me like you need to work on the team:
- motivate - find what's in it for them (celebrate process wins that save effort, explain to them the value of ITIl on their CV...)
- convert a champion or two to the cause - don't try to go it alone
- try to get a few stakeholders to sponsor and support (and fund) your efforts - a steering committee
- communicate, educate and train
- start measuring people - who opens the most?
Get the People right and they can all start fixing the Process.
Most of all you DON'T have a technology problem. Shoot anyone who tries to fix it with tools or webforms or... Remember:
technology does not fix process
