Knut Urdalen has written up a book review of a new release from the Packt Publishing folks - "Managing eZ Publish Web Content Management Projects" by Matrin Bauer.
I just went through it and this is the first book ever written about managing content management projects in general and using eZ Publish in particular. There's a lot of technical documentation and end user documentation about eZ Publish, but there has not been any documentation for project managers besides the more general project management literature.
He talks about the contents of the book - information on the phases of a project life cycle - and the level of technical knowledge that's required to understand it. He condones the book and recommends it specifically to project managers looking to get a bit more insight into what's happening with their eZ Publish projects.
