  6. 6. © 2022 Johanna Rothman @johannarothman “We need innovation! And we need to plan everything we’ll do for the next year!” 6
  7. 7. © 2022 Johanna Rothman @johannarothman Product development means we are all in the innovation business 7
  8. 8. © 2022 Johanna Rothman @johannarothman Innovation Outside In and Inside Out • Organizational strategy: problems we solve for which customers • Project and product portfolio: choices about which products to develop when • Every team’s product development 8
  9. 9. © 2022 Johanna Rothman @johannarothman How can we innovate when things take “so long?” 9
  10. 10. © 2022 Johanna Rothman @johannarothman We need innovation in our product development thinking 10
  11. 11. © 2022 Johanna Rothman @johannarothman Move from 12- to 8-Week Plan 11 8 weeks from Idea to Demo What Do You Think Occurred?
  12. 12. © 2022 Johanna Rothman @johannarothman What Really Happened 12
  13. 13. © 2022 Johanna Rothman @johannarothman “But We Use 2-week Sprints” 13
  14. 14. © 2022 Johanna Rothman @johannarothman What Happened in Those 2 Weeks 14
  15. 15. © 2022 Johanna Rothman @johannarothman Questions for the Chat • Please answer these questions in the chat: 1. How often do people collaborate on work, so two or more people work on the same piece of work? (Reduce WIP) 2. How often do you fi nish a feature? (approximately, because this is an indicator of throughput) 3. How often do you feel pressure to start more work? 15
  16. 16. © 2022 Johanna Rothman @johannarothman Little’s Law Explains Duration • The more work you have in progress, the longer it takes to fi nish it. • That increases the average lead time (cycle time) • This holds true at all levels of the organization 16 Average Lead Time = Average Work in Progress Average Throughput
  17. 17. © 2022 Johanna Rothman @johannarothman Dynamics of Little’s Law • The longer the team takes to deliver something, the more pressure to create larger and more extensive product plans (⬆WIP, ⬇throughput, ⬆cycle time) • The more product plans, the more pressure the team feels to increase throughput.They often start more work (⬆WIP) • Increased WIP delays all work they fi nish in any given time (⬇ throughput, ⬆ cycle time) • The lower throughput, the longer everything takes (⬆cycle time) • Everything takes longer. (⬆cycle time) 17 Average Lead Time = Average Work in Progress Average Throughput
  18. 18. © 2022 Johanna Rothman @johannarothman Everyone feels pressure Pressure reduces learning Since innovation requires learning, we get delivery, but not innovation 18
  19. 19. © 2022 Johanna Rothman @johannarothman Innovation Requires Fast Feedback • Short experiments • A customer/user/someone can see • Offer feedback to a person, team, and more 19
  20. 20. © 2022 Johanna Rothman @johannarothman Product Building Feedback Loops • Start faster with a shorter backlog • Get to done faster with: • Smaller stories • Collaboration • Release often to get feedback 20
  21. 21. © 2022 Johanna Rothman @johannarothman Roadmap Feedback Loops • Initial product strategy is an experiment! • Can change the backlog as often as: • Team completes a feature & demos • Customer offers feedback • Rolling wave planning, not big honking roadmaps 21
  22. 22. © 2022 Johanna Rothman @johannarothman Strategy Innovation with Shorter Feedback Loops 22
  23. 23. © 2022 Johanna Rothman @johannarothman Back-of-the-Napkin Feature Cycle Time Calculation • You can measure cycle time with a value stream map • Or, ask: • How many stories, fi xes, or anything else does the team typically fi nish in one, two, three, or four weeks? • Is your cycle time where you want it to be? 23
  24. 24. © 2022 Johanna Rothman @johannarothman Back-of-the-Napkin Roadmap Cycle Time Calculation • How much do you already have planned? • When can you decide to deviate from that plan? (roadmap cycle time) • Options for better roadmap cycle time: • Plan less in advance • Commit to “how little” and pull from below 24
  25. 25. © 2022 Johanna Rothman @johannarothman Product Roadmaps Are Not Like Car Roadmaps • How much rolling wave backlog planning does your org do now? • Too many product people use roadmaps that look like Gantt charts. Instead, choose one small MVP and then pull more work • (See the series that starts here: 2022/06/why-car-roadmaps-are-not- the-same-as-product-roadmaps- part-1/) 25
  26. 26. © 2022 Johanna Rothman @johannarothman Use Cycle Time for Durations, Never Story Points • Story points do not predict duration: • Ideal time • No understanding of essential and accidental complication • Does not account for delays • Cycle time does predict duration, especially when you measure over time 26
  27. 27. © 2022 Johanna Rothman @johannarothman How DoesYour Team Work? • Collaborate as in mobbing? ( fl ow ef fi ciency, fastest way to work) • Cooperate as in work together? • Totally separately? (resource ef fi ciency, slowest way to work) 27 Flow e ffi ciency
  28. 28. © 2022 Johanna Rothman @johannarothman Collaborative Team (Swarm) 28

  31. 31. © 2022 Johanna Rothman @johannarothman Value Stream Map When Team Works as Individuals 31
  32. 32. © 2022 Johanna Rothman @johannarothman How does your team work now? ( fl ow ef fi ciency or resource ef fi ciency?) Will that help you create more innovative products? 32
  33. 33. © 2022 Johanna Rothman @johannarothman The more team-based collaboration, the faster throughput and the more fun* 33 * In general
  34. 34. © 2022 Johanna Rothman @johannarothman Shorten All Feedback Loops for Innovation 34
  35. 35. © 2022 Johanna Rothman @johannarothman Fast Feedback for Innovation • Start one thing. • Finish it. • Do that again until you satisfy the customer. • Shorten all the feedback loops 35 Average Lead Time = Average Work in Progress Average Throughput
  36. 36. © 2022 Johanna Rothman @johannarothman What Product People Can Do • Ask team members to collaborate to reduce the team’s WIP. • Help the team pay attention to WIP. Ask:“What will help us get this story to done today?” • Instead of long roadmaps and large backlogs, ask:“How little can we do and still get a valuable result that will tell us what to do next?” • Monitor your leaders’ decision cycle time. Manage your WIP to support reduced organizational WIP 36
