Ken Schwaber (Scrum co-creator) describes this book as “extraordinarily competent”, which is a very appropriate description. Verheyen manages to cover Scrum comprehensively in just four chapters and really get to the heart of the why and what of the Scrum approach to product development.
For folks new to Scrum, there is probably not enough detail about the specific rules of the Scrum framework, but in that respect it makes the perfect accompaniment to the Scrum Guide. This book focuses more on the underlying principles of using Scrum to achieve agility and as such offers a far deeper understanding of the subject, for the new and more experienced Scrum practitioner alike.
I thought the observation of Scrum as the “gorilla of the Agile movement” was particularly helpful. This relates to Geoffrey Moore’s Technology Adoption Life Cycle. Verheyen observes that when, around 2007/8, the Agile moved from early adopters to more mainstream adoption, Scrum emerged as the market leader ‘gorilla’.
The book describes in intelligent detail, why Scrum achieved that position and how it is still holding its own in the fast changing world of software development.
