Russ,
I know what u mean when u say u know what the response times are, but other people may not. Its good to set expectations, otherwise people will expect 100% reliablilty 100% with support 100% of the time, we both know thats not likely, but ask your users, its what they expect.
I think the idea of management 'forcing' FITS is wrong. FITS isn't something u do to get paperwork or an award. Its something that if you genuinly do you'll get something back, usually more time.
There is still lots you can do with FITS even if there is only you doing IT Support. If anything, logging calls can only help you point out how much work u actually do.
I've worked with a few school who only have 1 person supporting the whole site. Its doable, I did it up to 3 years ago.
FITS is there to help you, its focuses on getting things done, in the quickest, most effective way possible, at the same time preventing you from reinventing the wheel.
For example, the section about corridoor management, where people just come up to you and give you jobs, that you end up forgetting about. Thats just bad practice, and FITS highlights this. Getting people to report incidents in a specific way that helps you to help them can only be a good thing.
FITS isn't prescriptive, you can make it fit (yeah i know) your organisation. For example we don't get staff filling out Incident Sheets, we do that for them.
But to say that FITS is not applicable is to ignore 25years of best practice & advice.
The guy I worked with when authoring FITS OM, Bob Lamb, told me about this IT guy who said that ITIL was just a waste of time, his responce was basically if you choose to do it any other way your choosing to mismanage your IT. Thats quite a strong statement, but he's a passionate guy, with ITIL.
