This publication is an essential addition to your arsenal if you are involved with ITIL v3.
At first viewing, this book can be quite daunting, until you realise that there is alot of padding included. A prime example is that when you apply for the ITIL v3 Expert Managers Bridging Exam, your trainer (in my case anyway) points out which sections to read. Whole chapters are left out! The exam is based upon an approved syllabus, so it speaks for itself.
However, I have to say that on some contracts/assignments the book made a good reference guide and was often referred to.
My only problem is that ITIL is now too big with many over lapping of roles and not many organisations will be looking to implement the entire framework.
It does all smack of financial enterprise now (RRP £85 for this book, part of a set) and they are now working on ITIL v3.1 which will no doubt mean more expense on updating qualifications, books, etc.
