Book excerpt: This book is for every PMO professional who would like to understand how to define and deliver a PMO service strategy. It is also intended as a study book for higher education in undergraduate and graduate degree courses in project, program, portfolio, and PMO management. Part 1 of the book contextualizes PMO management, exploring how to create and embed a PMO service catalog (including capabilities) to maximize the value of the PMO services. The concepts of domain of control, domain of influence, and domain of concern are introduced and used throughout the book. These concepts are also used as the basis for assessing PMO maturity and are integral to AIPMO's PMO maturity model. Also included in Part 1 are AIPMO's PMO services lifecycle framework, PMO service principles, and AIPMO's PMO competence framework, which connects PMO services to PMO capabilities. Part 2 of the book details 227 PMO services, from which the reader may choose to design or customize their own service catalog using the PMO service catalog methodology in Part 1. To aid the reader in the development of their PMO services, the author has provided insights as well as PMO service domain principles.
