  8. Kanban Supports the 7 Principles of Lean

  9. How does Kanban Compare to Scrum

  10. Roles Scrum Team Product Owner Scrum Master Kanban No Prescribed Roles

  11. Iterations Scrum Planning Review Retrospective Kanban • No Prescribed Iterations • Establish Cadences for • Planning • Process Improvement • Release

  20. Daily Meetings Scrum Daily Scrum FOCUS ON PEOPLE Kanban Not Prescribed Those that do FOCUS ON FLOW

  21. Measures Scrum Kanban

  22. Summary of Differences

  23. Can You Combine Scrum and Kanban to produce… “Scrumban”

  24. Can you Use Both? Note: “Scrumban” first introduced by Cory Ladas in his book ‘Scrumban”

  25. Cadence and Scrum • Scrum naturally implements a Cadence used in Kanban Cadence / Rhythms Planning Review Retrospective

  26. Can Scrum Pull? • The smaller the iteration – the closer Scrum is to a pull system • Use Iteration Backlog – Pull from Backlog • Plan on Minimal Marketable Features and SLAs Product Owner Scrumban dev test done ready 3 2 2 M J E A B K F N C G O D

  27. Limiting Work • Limit work by Sprint and by WIP using Story Points or Item Count (only works well with features about same size) Scrumban dev test done ready Reset Every Sprint 8-10sp 8-10sp 6-8sp M(3) J(5) E(3) Approximate Sprint Capacity A B K(3) F(3) N(5) C O(2) D Experiment with your team! Max SP could be: ItemCount * MinSize ItemCount * MaxSize

  28. Daily Standup in Kanban • Look at both Value flow and People flow Scrumban FOCUS ON PEOPLE FOCUS ON FLOW Best to use automated Tool to visualize work Which allows you to Pivot by Function and People

  29. Measure Velocity and Cycle Time Scrumban

  30. Other Considerations • Adding more States Add hand-off gates similar to Feature Driven Development Scrumban dev specify test done spec done ready 3 2 2 2 2 M n J p l A B o K q m N C O D Warning: Adding more states increases Work In Progress
