Last week I followed a course called ITIL v3 Foundations. During three days you get an overview of the ITIL principles and terminology.
If you're busy in the IT services world, I really advise you to follow the course. The things you'll see are usually logic and obvious but putting them all together give a more clear view over the whole process. Another useful extra is that you'll recognize and understand the terminology better. This terminology has become a kind of standard so it's not only 'yet new acronyms to learn' ;-)

Oh, btw, if you subscribe for this course at Dolmen during the summer you'll get the exam for free. More info here. Version 3 is currently given by Tom Segers, next to his daily consultancy for our customers he gives courses regularly and does a great job.
