This book leads with a single central principle - that a PMO's sole reason for existence is the creation of value for the organisation, and that the single most effective way it can do that is by managing the allocation of resources to projects. Of course, tools, methodology and processes are all good things to have, but identifying how to deploy resources for the best return on that investment is where a PMO really comes into its own.
I initially found such a forceful statement a little hard to swallow, but the book shows (using example scenarios drawn from the author's consulting experience) several ways how the PMO can fail if it chooses to focus its efforts in other directions.
If a PMO focuses on methodology, the PMs may superficially complete templates and processes just to keep the PMO quiet, but the completed templates and processes may bear little relation to reality. Unless the methodology is focused tightly on improving project delivery, this type of PMO merely increases administrative burden on PMs without enhancing value. Again, the PMO will be cut as soon as funding decreases.
The value created can be measured in terms of increasing the number of projects being delivered in a given time (since completed projects create value). As the availability of resources (people and/or money) is usually the single largest barrier to delivering more projects, increasing project delivery is often best achieved by creating a view of project and resource status to enable the most effective utilisation of resources across the project portfolio.
Well worth the purchase price.
