Organisational benefits of Project Management Maturity

This chapter by Dr Cooke-Davies examines some interesting questions about organisational maturity. It includes discussion of the question 'Is maturity an asset?' The conclusion is not an un-equivocal 'Yes', a lot depending on the context and dependence of the organisation on project management generally.
For those in the industry with an interest in promoting maturity models, there are important issues to ponder. For instance, how well do different maturity models actually confer benefit? Since most models evolve as experience in their use is acquired, there probably is no definitive answer.
This is a topic that deserves a lot more discussion.
