I've been following his erp4it blog for over a year now (and his corresponding erp4it YahooGroup). Those looking for a taste of what the book is like can look there, and also at the paper ERP for IT which I understand was an early precursor for the book that has since been vastly updated and expanded in the latter.
Even though the subject of the book and the blog doesnt explicitly scream "CM", the content in the book and the blog are filled with often fundamental and profound insights about CM from the enterprise view (not just IT/ITIL) and where software CM, infrastructure CM, and network/element CM all fit in to the bigger enterprise picture. Several of his post that are among my favorites made their way into the book in some form or another:
- A Data Architecture for IT Service Management -- you'd never know it from the title, but this is practically a primer on what is a configuration and what is a configuration item (and much more)
- A Configuration Management Maturity Model
- Element versus Enterprise CM
- Two key distinctions to help scope your CMDB -- about the difference between Configuration Items and Events (quick - what's the difference between a "release" and a "baseline"?)
- Is CM a process?
- DBMS Configuration Management -- and the difference between Software CM, Element CM and Enterprise CM
- Model-Driven CM
- A Value-chain approach to IT
- A simplified ERP for IT architecture -- the CM system figures prominently in this one
- IT portfolios, service catalogs, and enterprise architecture -- change management (at all levels of scale - including governance) links them all together across the value-chain
- Fundamentals of integration metadata
- A story of too many tools
- A metadata rant
- CMDB Chaos and Confusion: Making Sense of the Madness
And if that weren't enough, the book also puts together three of my favorite topics: CM, patterns, and architecture.
