I suppose I should throw in my two cents.

Primarily, I'm a business workflow efficiency consultant specialising in medium to large IT helpdesks and other teams which have similar ticketing/workflow setups (call centres, other IT teams, admin areas etc). I can usually knock off about 50% of the running costs while making the working environment a heck of a lot better for the techs and a lot less stressful for everyone. Turns out a lot of Helpdesk and Service Desk teams get really easily bogged down in old policies and procedures without realising it.

I pretty much just go in and detangle everything, then get the bosses to fix all the things that the techs have identified as problems. It turns out that bosses are a lot more willing to listen to you if you wear a suit, talk in terms of dollars and man-hours, and charge half a million bucks a week - even if you're repeating exactly the same things that the techs have been saying for years. And yes, I can show the financial advantages of things like nice furniture, multiple screens/PCs per tech, advanced diagnostic software, paid industry cert training, high tech salaries etc.

To keep my hand in, I also take on contract roles as an actual IT helpdesker. Hey, it's what I've been doing for over ten years, so I'm not too bad at it. It also gives me the excuse to evaluate a helpdesk from the inside and ferret out the particular local causes of stress and inefficiency, so I can then offer a comprehensive capacity improvement project to the Powers That Be when my time's up.

I write monthly articles for a national Helpdesk industry publication. It's more about getting my name out there than being paid, though.

In my spare time, I invent things, or at least conceptualise them and run them past a local thinktank with links to manufacturers.
