Kanban is a system for managing workflow using visual signals. It uses cards to represent work items as they move through different stages of a process from input to completion. The goals of Kanban are to improve the existing process without changing roles or workflow, and to enable easy adoption. Kanban boards visually depict the workflow using columns for each stage and cards that move from left to right as work is completed. Work items, lead times, and buffers between stages are identified to model the process.

Kanban intro
- 1. AMIR BARYLKO WHAT IS KANBAN? Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 2. INTRO Kanban System Pull vs Push Goals Software Process Example Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 3. KANBAN SYSTEM •Kanban = Signal Card •Kanban cards represent the capacity of the system •Each card is a “signal” •No work can be started unless has a card available •The card gets attached to a work item Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 4. PULL VS PUSH New work is New work is pulled pushed into the system into the system based on based on capacity demand Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 5. GOALS • Improve your current process • Not change roles • Not change flow • Easy adoption Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 6. SOFTWARE PROCESS • Cards are “virtual” • Cards represent a work item • The system is represented by a card “wall” • Pull is signaled when the work-in-progress is less than the actual limit • Often implemented with sticky notes and a board Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 7. KANBAN BOARD Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 8. MODEL YOUR PROCESS Identify Workflow Drawing the board Time Calculation Buffers Work Items Amir Barylko > Kanban > What’s Kanban? MavenThought Inc.
- 9. IDENTIFY WORKFLOW •Which states/phases can be possible? •What are the transitions? •Which roles are involved? •Which are the boundaries? Amir Barylko > Kanban > Implementation MavenThought Inc.
- 10. EXAMPLE Analysis Testing Design UAT Coding Deploy Amir Barylko > Kanban > Implementation MavenThought Inc.
- 11. WORK ITEMS • Use Cases • User stories • Bugs • Change request • Etc.... Amir Barylko > Kanban > Implementation MavenThought Inc.
- 12. BOARD / CARD WALL • Each phase/state becomes a column • Has a first input column (usually called backlog) • May have a last archive form done items • The flow goes from left to right • By convention highest priority goes on top Amir Barylko > Kanban > Implementation MavenThought Inc.
- 13. EXAMPLE BOARD Input Analysis Design Coding Testing UAT Deploy Flow Amir Barylko > Kanban > Implementation MavenThought Inc.
- 14. LEAD TIME • Starts when the card is added to the input queue and finishes when is delivered/deployed Input Analysis Design Coding Testing UAT Deploy Lead Time Amir Barylko > Kanban > Implementation MavenThought Inc.
- 15. CYCLE TIME • Startswhen work begins on the card and finishes when the card is ready to be deployed Input Analysis Design Coding Testing UAT Deploy Cycle Time Amir Barylko > Kanban > Implementation MavenThought Inc.
- 16. BUFFERS • Identify cards that are ready • But can’t be moved to the next phase • Usually shown as “done” • or marked with different color Amir Barylko > Kanban > Implementation MavenThought Inc.
- 17. BOARD WITH BUFFERS Backlog Analysis Coding UAT Deploy Archive In Prog. Done In Prog. Done Amir Barylko > Kanban > Implementation MavenThought Inc.
- 18. WORK ITEMS • Do all the work items have the same workflow? • How can we identify them? • Use different colors • Or different rows (swim lanes) • Or both Amir Barylko > Kanban > Implementation MavenThought Inc.
- 19. USING SWIM LANES Backlog Analysis Coding UAT Archive In Prog. Done In Prog. Done Features Bugs Small Change Amir Barylko > Kanban > Implementation MavenThought Inc.
- 20. WHAT GOES IN THE CARD? • Information about the feature/request • Number for traceability (tracking system, etc) • Who’s assigned • Deadline • Other? Amir Barylko > Kanban > Implementation MavenThought Inc.
- 21. Post-It DRAW YOUR BOARD & Sharpie! • Split up in teams (2 or 3) • Identify current workflow • Identify work items • Draw a board • Discuss Amir Barylko > Kanban > Implementation MavenThought Inc.
