何が書かれている本か
Jeff Sutherland と James "Cope" Coplien が書いた本で 2019年出版
Jeff Sutherland は、 OOPSLA'95 で Ken Schwaber と共同でスクラムの発表をしたスクラムの作成者の1人
James "Cope" Coplien は、PLoP (Pattern Languages of Programs) というパターンランゲージのコミュニティの運営者
そのスクラム版として派生した Scrum PLoP (Pattern Languages of Programs) というコミュニティにより議論されたものをその時点で本として出版したもの
Q&A on A Scrum Book: The Spirit of the Game の中でも、
The Scrum Guide focuses on what Scrum is, but the real magic comes from the way you implement it. The fundamental concept of Alexander of generating wholeness from patterns seems to me both right and profound. I wanted to help describe how to create great Scrum teams that are both hyperproductive and life-changing for the participants.
と述べていて「スクラムガイド」がルールを表すのに対して、この本ではパターンについて整理することでどのようにプレイするかということが書かれている本となっている
ちなみに本の内容はほぼ全部ここで読めるので買う必要は割とない

余談で、 Scrum@Scale は Jeff Sutherland が発案者でこういうパターンが構造に現れていて自分は好きです

これだけ形式違うのなぜ
1. First, just get started. Start with Stable Teams.
2. Next, decide how you are going to size your releases every Sprint. Start developing and establish a velocity (see Notes on Velocity) and bring it into statistical control: use Yesterday’s Weather.
3. Next, work on getting stuff Done (see Definition of Done) instead of foundering in rework. It takes teamwork to do that. Use the pattern Swarming: One-Piece Continuous Flow.
4. Interruptions are one of the largest potential killers of velocity. You need to know how to deal with interruptions during the Sprint. We presume you have a ScrumMaster, but you need a more finessed technique that suggests a framework of discipline to make interruptions visible and structure how you deal with them. Try Illegitimus Non Interruptus.
5. Focus on quality from the beginning, every day. Early on, strive for Good Housekeeping.
6. Stuff happens, and dealing with emergencies is a discipline. Align the organization to deal with emergencies using the disciplined replanning of Emergency Procedure.
7. The heart of Scrum is process improvement. Get into a rhythm of improving your process every Sprint with Scrumming the Scrum.
8. Part of improving is to measure—but measure more with heart than with raw numbers. Drive forward with the Happiness Metric.
9. Revisit how you are sizing your Sprints. Instead of pushing the team to take more and more into the Sprint, refocus on Yesterday’s Weather and give yourself room to improve. Try Teams That Finish Early Accelerate Faster.
