This book is about how to run services, in any organisation, in any industry. It describes the basics, the core stuff, in realistic pragmatic terms. And it is pragmatically brief - we kept it to 50 paperback pages.
If you think ITIL blew out in the 2011 edition, you should see MSP (Managing Successful Programmes). 150 pages becomes 300. Doubled! Given that nobody reads anything any more, is BoK (body of knowledge) Bloat a problem or not?
