Presented at Agile Bath & Bristol (21st March 2017)

If software development is a co-operative game, as Alistair Cockburn observed, then what kind of game is Scrum? Lots of people are playing it — or say they are — but there seems to be some disagreement about what the point of the game is, how to play it and even, in many cases, what the rules are. This talk looks at Scrum and other agile approaches through the lens of nomic games, hypothesis-driven development and fun.

Game of Sprints

  1. 1. Game of Sprints @KevlinHenney
  2. 2. https://theculturetrip.com/north-america/usa/new-york/ articles/10-paces-to-find-street-art-in-nyc/
  3. 3. They satirized the reductive and banal nature of management speak. Will Gompertz Think Like an Artist
  4. 4. Scrum works by making visible the dysfunction and impediments that are impacting the Product Owner and the team’s effectiveness, so that they can be addressed. The Scrum framework will quickly reveal these weaknesses. Scrum does not solve the problems of development; it makes them painfully visible, and provides a framework for people to explore ways to resolve problems in short cycles and with small improvement experiments. http://scrumprimer.com
  5. 5. It has become commonplace to suggest that failure is good for entrepreneurs. In this view, failure that comes early in a founder's career can teach them important lessons about doing business and harden them up for the next start-up attempt. David Storey "Lessons that are wasted on entrepreneurs" http://www.ft.com/cms/s/0/fb24f8a4-2151-11dd-a0e6-000077b07658.html
  6. 6. In the UK, the evidence is that novices are neither more nor less likely to have a business that either grows or survives than experienced founders. In Germany, where much more extensive statistical work has been undertaken, it is clear that those whose business had failed had worse-performing businesses if they restarted than did novices. David Storey "Lessons that are wasted on entrepreneurs" http://www.ft.com/cms/s/0/fb24f8a4-2151-11dd-a0e6-000077b07658.html
  7. 7. In short, the assumption that entrepreneurs use the lessons of their own experience to improve their chances of creating a series of profitable businesses is not borne out by the evidence. Success in business remains, as in life, something of a lottery. David Storey "Lessons that are wasted on entrepreneurs" http://www.ft.com/cms/s/0/fb24f8a4-2151-11dd-a0e6-000077b07658.html
  8. 8. Man prefers to believe what he prefers to be true. Francis Bacon
  9. 9. No matter what humans think about, we tend to pay more attention to stuff that fits in with our beliefs than stuff that might challenge them. Psychologists call this "confirmation bias." When we have embraced a theory, large or small, we tend to be better at noticing evidence that supports it than evidence that might run counter to it.
  10. 10. As any psychologist will tell you, pretty much everything you think and do is coloured by biases that you are typically totally unaware of. Rather than seeing the world as it is, you see it through a veil of prejudice and self-serving hypocrisies. http://www.newscientist.com/article/ mg21028122.200-the-grand-delusion-blind-to-bias.html
  11. 11. You have just experienced the illusion of naive realism - the conviction that you, and perhaps you alone, perceive the world as it really is, and that anybody who sees it differently is biased. http://www.newscientist.com/article/ mg21028122.200-the-grand-delusion-blind-to-bias.html
  12. 12. If, at this point, you are thinking: "Yeah, right, that might be true of other people, but not me," then you have fallen foul of yet another aspect of the illusion: the bias blind spot. Most people will happily acknowledge that such biases exist, but only in other people. http://www.newscientist.com/article/ mg21028122.200-the-grand-delusion-blind-to-bias.html
  13. 13. If you want to learn how to build a house, build a house. Don't ask anybody, just build a house. Christopher Walken
  14. 14. empirical, adjective  based on, concerned with, or verifiable by observation or experience rather than theory or pure logic  pertaining to, or derived from, experience  capable of being verified or disproved by observation or experiment Concise Oxford English Dictionary ∙ Oxford English Dictionary ∙ Merriam-Webster's Collegiate Dictionary
  15. 15. The "defined" process control model requires that every piece of work be completely understood. Given a well- defined set of inputs, the same outputs are generated every time.
  16. 16. The empirical process control model, on the other hand, expects the unexpected. It provides and exercises control through frequent inspection and adaptation for processes that are imperfectly defined and generate unpredictable and unrepeatable results.
  17. 17. Plan Establish hypothesis, goal or work tasks Do Carry out plan Study Review what has been done against plan (a.k.a. Check) Act Revise approach or artefacts based on study Deming/Shewhart Cycle
  18. 18. Starting from a position of incomplete knowledge and gradually iterating through hypothesis, experiment and discovery towards — one would hope — working software addresses part of the question of moving from the unknown to the known. Kevlin Henney "The Uncertainty Principle" NDC Magazine 2009
  19. 19. If a plot works out exactly as you first planned, you're not working loosely enough to give room to your imagination and instincts.
  20. 20. / WordFriday
  21. 21. pantser, noun  Writer who writes by the seat of their pants.  In contrast to a plotter, a pantser doesn't work to (or have) an outline.
  22. 22. Plan Establish hypothesis, goal or work tasks Do Carry out plan Study Review what has been done against plan (a.k.a. Check) Act Revise approach or artefacts based on study Deming/Shewhart Cycle
  23. 23. Write As the behaviour is new, the test fails Reify Implement so that the test passes Reflect Is there something in the code or tests that could be improved? Refactor Make it so! Test-First Cycle
  24. 24. TDD is fun! It’s like a game where you navigate a maze of technical decisions that lead to highly robust software while avoiding the quagmire of long debug sessions. With each test there is a renewed sense of accomplishment and clear progress toward the goal. Automated tests record assumptions, capture decisions, and free the mind to focus on the next challenge. James Grenning Test-Driven Development for Embedded C

James Grenning Test-Driven Development for Embedded C
  27. 27. Rock climbing, story-telling, and carpet wrestling are not about winning or losing; the game is all about having fun. As long as the guessing or the story-telling is interesting, the game is worth playing. These are cooperative games. The point of the game is to interact with each other, or perhaps to help each other. Alistair Cockburn "Software Development as a Cooperative Game" http://alistair.cockburn.us/Software+development+as+a+cooperative+game
  28. 28. / WordFriday
  29. 29. nomic, noun & adjective  a game in which changing the rules of the game is a legal move and part of the game  the original Nomic was invented by Peter Suber, but the term is now generalised to describe any game that has these properties  political constitutions, legal systems, software development processes and many games that children spontaneously evolve over an afternoon of play are nomic in nature
  30. 30. Software development: a social activity with technical practices. Helen Sharp
  31. 31. The four conditions that characterize wise crowds: diversity of opinion, independence, decentralization, and aggregation.
  32. 32. There’s little correlation between a group’s collective intelligence and the IQs of its individual members. But if a group includes more women, its collective intelligence rises. "What Makes a Team Smarter? More Women" http://hbr.org/2011/06/defend-your-research-what-makes-a-team-smarter-more-women/
