In 2010, the principal co-creators of Scrum, Jeff Sutherland and Ken Schwaber, agreed on the first version of the Scrum Guide, thereby creating the official BOK (body of knowledge) for Scrum. A few small, functional updates have been released since then. There have been no drastic changes to the core definition of Scrum. The updates that were released reduced complexity of the Scrum Guide or introduced clearer terminology. Language and words do matter.
The Desire for Precision
I imagine the difficulty of every rephrasing involved in updating the Scrum Guide. The Scrum Guide holds the single definition of Scrum for countless practitioners across the world, all employing Scrum in unique environments and varying situations. I imagine the discipline of updating the Scrum Guide knowing that many people will not read it. Most of all, I imagine the difficulty of updating the Scrum Guide knowing that many will micro-dissect the texts to identify the tiniest of changes. Many over-think individual words upon the misassumption of traps, tricks and hidden messages. Many still look for methodological exactness and universal precision.
Regardless, the fact that Scrum has a clear and documented definition is priceless. The Scrum Guide provides clarity and purpose, albeit not the perfect precision that many seem to look for.
Scrum is a tool. Useless unless employed.
The Scrum Guide intentionally has no universally applicable, detailed instructions or tactics that in the end only work in specific circumstances. The Scrum Guide describes how the tool works, the rules and roles that apply, the behaviors that make the tool work; not the tactics to apply the rules. Scrum, by design, offers room and breathing space, inviting people to conceive an approach specific to their context upon the empirical foundation of Scrum. Scrum is a framework, not a traditional (IT) methodology. The Scrum Guide describes the framework, the minimal boundaries within which people deal with complex challenges and create complex solutions in complex circumstances.
All exact decisions within those boundaries depend on people, tools, technology, business domain, organizational environment, market situation, and many other aspects.
What is the availability of people? Their skills, experience? How well do teams gel? Do they work remotely, or co-located? How long have they been working together? How much multi-tasking does a team or team members have to do? How well are teams facilitated by the environment? What technology is being used? Which version? What dependencies are at play? What development practices does a team have in place? What tools and infrastructure are at the teams’ disposal? How long are the Sprints? How is the connection with product management? What is the competition doing?
Scrum does not have the false pretence nor ambition to offer universal truths, universal answers that apply in every single situation. Scrum essentially invites people to regularly match the actual state of their work against reality, in order to optimize flow and progress, while re-aligning and adapting to new circumstances, highly disruptive events and new insights. Scrum is a simple framework for complex product delivery.
The Scrum framework offers the simplicity needed to address complex challenges, without being simplistic about the unique and specific problems that teams and organizations face. Many people struggle with this deliberate imprecision when they try to improve their understanding of Scrum. They look for detailed instructions. They ask universal questions and demand exact and precise answers.
How long should Sprint Planning be? And the other events? How much time does the Product Owner role take? Is the Scrum Master role a full-time job? Should a team be available full-time? How must we organize when the team is distributed? How much time of a Sprint should a team spend on testing? How many business analysts are needed in the team? How should we calculate utilization? How can we measure productivity? Should the Product Owner and the Scrum Master understand the technology? What if… ?
No document, no matter its length, can provide exact answers to all of these questions for all Scrum practitioners of all workplaces around the world. It requires skilled professionals (Scrum Masters, trainers, and otherwise) to build on the language and words provided by the Scrum Guide and explain intent and purpose. It requires courageous professionals to help teams, organizations, and students grow an understanding of how Scrum supports them in empirically dealing with the diverse, complex challenges they face in their real-life complexity. Such professionals understand that what works today might not work tomorrow. Exact instructions lead people astray, undermine their ability to think autonomously in terms of Scrum. It is highly disrespectful. Answers to the ‘what if’ questions will emerge from the use of Scrum, from the inspections performed in Scrum. Be prepared to learn and adapt.
My personal stance, as a trainer, a friend, a trusted advisor, a whatever in Scrum, is to facilitate people in understanding the purpose of the rules and the roles of Scrum. This is at the heart of my book, Scrum – A Pocket Guide, and all my actions of promoting and explaining Scrum. The only viable way forward for people is to devise their own solutions employing Scrum. No external instance, expert or otherwise, can or should do that for them. It may be tempting. It is certainly highly convenient. It might make a person appear knowledgeable. But it promises certainty where there isn’t. That is unprofessional. It ignores context and complexity. It ignores people’s intelligence and creativity.
Every case of Scrum is unique. There is no copy-paste. There are no universal truths in the complex novelty space. The definition of Scrum requires no methodological precision. There is no future in ignoring complexity.
