- 11. And stories come from Product Owners
- 12. (typically) And “ stories ” come from ^ Product Owners
- 13. I see Product Owners that spend a lot of time writing stories 1 As a … I want … so that Given … when … then …
- 14. spend a lot of time grooming a backlog 2 more work on stories - prioritising, dressing them up ...
- 15. spend some time in sprint planning 3 confirming the content of stories
- 16. 4 always sit in on sprint review compares output (software) to input (stories)
- 17. dealing with stakeholders 5 giving and receiving information
- 18. PO has a strong story focus write stories (and/or scenarios) 1 As a … I want … so that / Given … when … then … groom backlog 2 more work on stories give input for sprint planning 3 more about stories sit in on sprint review 4 compares output (software) to input (stories) deal with stakeholders 5 giving and receiving information do a lot of (other) planning too ...
- 19. But it is an unbalanced state It has the overall effect of an instruction or “here, now do this”. most of the time, this is accidental! Instead of encouraging the team to collaborate with the PO, it creates a “hand-off”.
- 20. Watch out for some of the signs Sprint planning is a Q&A session Team: “Where do you want that checkbox?” 1 PO: “Next to the drop down”
- 21. PO is doing design or passing on 2 someone else’s design. “They said they need a new operation on the StockQuote web service. Here’s what they sent ...”
- 22. PO becomes the bottleneck 3 “My backlog is too big and never seems to shrink”
- 23. What can a PO try? 1 Spend less time formalising stories Spend more time talking with the team. “We need to give our customers a way to …” “You are right, it does matter if we …” “I’m happy to defer that edge case to the next sprint.”
- 24. What can a PO try? 2 Provide feedback about product knowledge “No, it’s not about how long they take to complete the registration. We’re asking for the wrong information when they register.”
- 25. What can a PO try? 3 Give feedback on product implementation options “If you can implement the second UI mockup you showed me, our customers will be over the moon.” “The way you proposed to do the calculation will be ok for our smaller funds. Let’s go with that for this sprint, even though it may be inefficient for our really big funds.”
- 26. Pop philosophy for POs 4 Trust the team and reciprocate that trust How about the PO doing the sprint review to all stakeholders? 5 The mood of the PO permeates deeply into the team. Feeling skeptical about the product? The team will feel it. Feeling good about the product? The team will feel it.
- 27. Let’s go back to necessary and sufficient?

- 29. The team is the other side of the hand-off from the PO If we understand the hand-off and it’s subtleties then the team behavior becomes clearer.
- 30. When a PO does a hand-off then the team is expecting a fully dressed story to be received ... then design starts getting less attention ... then understanding, purpose and intention starts to disappear ... and if the sprint review goes badly, then the story (or the PO?) was wrong.
- 31. What can teams try? 1 Work towards increasing understanding by having meaningful conversations with the PO and anyone else as needed. And if you like BDD stories in your project, let the team write them.
- 32. What can teams try? 2 Give feedback to the PO on possible solutions to a problem. This is not casting a design in stone. It is an opportunity to confirm your understanding, in more ways than one. Alternatives are good.
- 33. But! here’s a big challenge Web Page Title G http:// oo domain.com gl e __ / __ / ____ Select a date range A ab Format Font Size 1 B i u 2 3 enter text or Cancel Done what we commit to build done need tiny bit what's next? Shrunk from, perhaps, months to weeks
- 34. Web Page Title G http:// oo domain.com gl e __ / __ / ____ Select a date range A ab Format Font Size 1 B i u 2 3 enter text or Cancel Done what we commit to build done need tiny bit what's next? Can’t just crank out code like before. - drive design with tests. - automate as much as you can tolerate. - write just enough, and nothing more. It’s the stuff that Kent writes about :-)
- 35. SO what about Scrum Masters?
- 36. My observations Scrum Masters get a lot of early attention when starting out with Scrum. They are the keepers of the faith. They are agents for establishing a cadence in the workflow.
