This is the best book about Modern Scrum that you will find anywhere! This is the Second Edition of the book, and it has been updated to include the latest, and greatest, information about Scrum. Scrum is the world's most popular Agile Development Framework, and it has been changing constantly since its discovery in 1995. Over the years, Scrum users have found what does (and does not) actually work, and the Scrum Framework has changed to keep up (part of Scrum's own inspect and adaptprocess). The rate of change has slowed down over time and, as of late 2013, there is hope that Scrum has stabilized. This book presents that stabilized version of Scrum, along with discussions of why and how it got that way. Dan and Doug wrote this book in order to help people with their implementations of Scrum, and to make sure they have the most current understanding of Scrum to work with. They have found that many of the ideas found in older versions of Scrum are not only out-of-date, but harmful. Both Dan and Doug have trained and coached thousands of people, most of whom are already using Scrum. In spite of the fact that they have read about Scrum, have been trained or coached in Scrum, and are using Scrum, their most common complaint is that they need help to do it 'right'. Dan and Doug have found that many (if not most) of them need some help. This book is for them and others like them. This book is not an introductory text. Dan and Doug assume that those who read this book know, or think they know, something about Scrum. This book takes a deep, exploratory, look into the Scrum framework (as it has changed over time), and offers advice about how to think about it, and how to use it. Some of this advice is philosophical, some is pragmatic, and all of it is practical. Dan and Doug are brutally consistent and true to the essence of Scrum. This book is not the result of an academic exercise; every suggestion or conclusion in this book is grounded in real-life issues they have encountered, and suggestions that they have made for teams and people they have coached or trained.
