hypothesis driven development
- 3. problems we’ll tackle today perfection the past
- 4. why is perfection bad?
- 6. bring me solutions, not problems
- 8. kodak
- 9. was kodak a fluke?
- 10. the six sigma experiment errors ideas
- 11. why is perfection bad? too much perfection (six sigma) can cause us to miss big opportunities (kodak) and avoid new ideas (unsolved problems)
- 12. why is the past bad?
- 15. it’s the way we’ve always done things
- 16. why is the past bad? it stops us from seeing other possibilities
- 17. how might we find more opportunities and new possibilities?
- 18. bertrand russell it's a healthy thing now and then to hang a question mark on the things you have long taken for granted
- 19. assumptions backlogs are things to do we learn so that we can execute we need to predict (effort, ROI, etc.), to prioritize
- 20. assumptions as questions what if our backlog was things to learn? what if learning and executing were the same? what if we prioritize learning based on the value we think it leads to? how might we…
- 21. smart people
- 22. use questions
- 23. bring me problems, not solutions
- 24. what got us here, won’t get us… …somewhere else
- 25. how might we find more opportunities and new possibilities? explore questions rather than doing what we know
- 26. how might we make a question backlog?
- 27. closed questions as a call center support technician i want search fields for name and zip code so that I can quickly get the caller's account info can we more quickly get account info for call center support techs by asking clients for a name and zip code?
- 28. avoid known answers can we add a new workflow state by adding it to the state table and creating a workflow in the transitions table? can we allow users to edit states by creating an admin utility?
- 29. answerable questions as an Engineer i want code coverage of 80% so that our product quality will be improved can we Improve product quality by increasing code coverage to 80%? can we reduce reported issues by 50% by increasing code coverage to 80%?
- 30. can we [...] by [...]
- 31. can we [...] for […] by [...]
- 32. how might we make a question backlog? answerable closed questions can we […] by [...] .
- 33. how might we write better questions
- 34. open & close to craft better questions it is difficult to talk to bob. why is it difficult to talk to bob? is it difficult to talk to bob? why is it difficult to talk to bob, for me?
- 35. open & close to craft better questions we want better quality. do we want better quality? why do we want better quality? can we reduce late night calls, by regression testing every release candidate?
- 36. how might we manage a question backlog?
- 38. who wants to learn this > who best to do this?
- 39. answer the question (this is kind of your job)
- 40. yes = proof (working software)
- 41. no ≠ failure
- 42. can we […] by […] check yes no run experiment write new question(s) write new question(s)
- 43. To Do Doing AnsweredChecking
- 45. team learning
- 46. how might we manage a question backlog? like today, but with less certainty and with more learning
- 47. lao tzu we mold clay into a pot, but it is the emptiness inside that makes it useful
- 48. has this ever worked?
- 49. my life as a vb6 engineer control triplets for pick lists can we make this better by using a control? lots of code to bind UI controls to data fields can we link controls to data fields by adding properties to controls? copy paste code to call stored procedures can we automate server code by generalizing the logic? copy paste modules for new features can we automate workflows by using modules & classes?
- 50. how might we try the idea safely?
- 51. can we validate these ideas by testing them in a safe place? inspect for learning retros training innovatriums leadership teams try an experiment
- 53. avoid the perfection trap too much perfection (six sigma) can cause us to miss big opportunities (kodak) and avoid new ideas (unsolved problems) can we […] by […]
- 54. what you know is holding you back
- 55. bertrand russell it's a healthy thing now and then to hang a question mark on the things you have long taken for granted

- It’s your job to know the answer
- 1975
- a 2006 Fortune assessment found that 91% of companies that had implemented lean six sigma, had failed to keep pace with the S&P 500 in the years after adopting the program
- http://www.npr.org/sections/health-shots/2014/05/05/308349318/you-had-me-at-hello-the-science-behind-first-impressions After the first word you speak, you can be assessed on 10 dimensions and will be measured with shocking consistency
- Innovation can get stalled when people don’t know what to do Innovation can get stalled when people give up too easily because they don’t know the next step using answers (stories, specs, etc.) will only help you to do more of what you already know using questions can help you try new things and be ahead of the curve
- What we know is a liability as much as an asset. Question where we are and how we’re doing it to figure out what’s next
- Ask "what if" to find our hypothesis Ask "how might we" to find a starting point

- No learning for learnings sake. Not, ”I saw this in a blog” If you haven’t applied it and proven it, there is no definitive answer.
- At the end of a sprint, the core question is not "what did we finish", it is "what did we learn" Getting an answer of "no" is not the same thing as failure - it is a perfectly valid answer. The trick to a "no" is that it should probably result in a new question that has been refined by what we learned. Failing forward
- Ask more questions Prioritize Iterate For each question you do (or don’t) answer, you may find yourself making several more. This pattern allows you to keep going deep where warranted rather than just trying to keep moving along.

- If the team plans growth, they can help each other grow
- turn a few items into questions see how much learning is there write retro items as questions - in the next retro, look at what answers (or new questions) have emerged

- We've become experts at evaluating our ability to deliver. I've been in many a conversation about such metrics, or about these topics and there is one theme that never comes up. What did people learn? What skills are we developing? Are we preparing the team to be able to do what we aspire for?
