Kanban is a method for the process improvement. It has 5 simple core principles and can be applied to any software development process - either some agile methodology or the pure waterfall model.

Transcript

  • 1. Kanban Overview Vít Kotačka, ICS Team Leader 6. 11. 2013
  • 2. What is Kanban? Kanban is a method for managing knowledge work with an emphasis on just-in-time delivery while not overloading the team members. In this approach, the process, from definition of a task to its delivery to the customer, is displayed for participants to see and developers pull work from a queue. (source Wikipedia) In software development, we are using a virtual kanban system to limit (team's) work-in-progress ... to a set capacity and to balance the demand on the team against the throughput of their delivered work. By doing this we can achieve a sustainable pace of development so that all individuals can achieve a work versus personal life balance. (source Kanban by David J. Anderson) 2
  • 3. What Kanban Is Not? Kanban is not: a methodology. a process (for software development). an agile practise. a project management tool. a silver bullet. 3
  • 4. Benefits of Kanban It eliminates waste from the process. Reducing work-in-progress improves quality. Improved quality improves trust with downstream partners. Process improvement leads to greater productivity and greater predictability. It enables incremental changes with reduced political risk, with minimal resistence. It provides transparency on both the work and the process through which the work flows. Individuals are more likely to give of their time and collaborate when they can see the effect it will have. (source Kanban by David J. Anderson) 4
  • 5. Origins of Kanban Toyota Production System (TPS) Lean Software Development Drum-Buffer-Rope (DBR) methodology (picture source: Wikipedia.org) 5
  • 6. Five Core Properties 1. 2. 3. 4. 5. 6 Visualize Workflow Limit Work-in-Progress Measure and Manage Flow Make Process Policies Explicit Use Models to Recognize Improvement Opportunities
  • 7. Visualize Workflow Split the work into pieces, write each item on a card, and put the card on the wall. Use named columns to illustrate where each item is in the workflow. (source Lean from the Trenches by Henrik Kniberg) 7
  • 8. Limit Work-in-Progress Assign explicit limits to how many items may be in progress at each workflow state. (source Lean from the Trenches by Henrik Kniberg) 8
  • 9. Measure and Manage Flow The flow of work should be measured, so the continuous, incremental changes to the system can be evaluated. Cumulative Flow Diagram is very offen used for visualization. 9
  • 10. Make Process Policies Explicit There should be explicit definition and understanding of the (project) policies, so that issues can be rationaly and objectively discussed, mitigated and improved. Policies can be about: Definition of Done (DoD) Work-in-progress (WIP) Issues addressing and escalation Responsibility during process states 10
  • 11. Use Models to Recognize Improvement Opportunities By modeling the workflow of a software development lifecycle as a value stream and then creating a tracking and visualization system to track state changes of emerging work as it „flowed“ through the system, I could see bottlenecks. The ability to identify a bottleneck is the first step in the underlying model for the Theory of Constraints. (source Kanban by David J. Anderson) Common models are: Theory of Constraints (the study of bottlenecks) Deming System of Profound Knowledge (a study of variation) Lean economic model (concept of „waste“) (source Wikipedia) 11
