The book is quite heavy, but it is worth it. The design encourages you to immerse yourself in the content and details. Attractive cool and warm colors are used effectively to enhance visual appeal, aiding in reader engagement and comprehension. The font size is perfect, making it easy to read. 

However, the cover design could be more engaging. The picture could better reflect the concepts of Service Domains, Service Groups, and Services.

The text is easy to understand, with consistent headings. The language used is just right and helps readers grasp the content. Additionally, the organization of domains and the clustering of services offer insight into the thought process behind the book and PMOs. The book covers over 200 services, with each service following the same format. This format works well as a reference for specific services. However, for someone new to heading a PMO and seeking potential services to offer, reading the entire book can be overwhelming.

The PMO capabilities table could be challenging to read, particularly column three, which includes Service Domains Competences, but overall, readers can easily skim through any part of the book based on their needs.

The steps in designing the services catalog are a key feature, helping the practitioner decide which services to select. All the services applied to the field of study are ideally referenced and include examples with case studies. Although it doesn’t offer full details of every service but you can find enough reference for further reading. 

Some referenced materials are outside the project management domain but are valuable to the field. This new approach to project management and project management office broadens the knowledge base and creates advantages for companies. It also makes it easier to convince non-project professionals to trust the process, as they can relate to the language.

Two additional elements make the book a significant added value in the real world. First, under each service, there is a section titled “How the PMO will apply this service?” where the author provides details on implementing the described service. Second, the presence of the “Tips” and “Insight” sections throughout the book, where the author provides practical additional information and views that are very useful when implementing the content. 

The book offers a solid framework for PMO implementation, value generation, and maintaining the PMO. The book excels in various aspects, such as the consistency of research/referencing, detailed implementation steps for services, and practical information provided in tips and insights sections.

The model, with its incorporation of clusters, service domains, service groups, and services, demonstrates innovation. However, upon closer examination of the services themselves, they may not necessarily challenge established norms to a significant extent.
