WIP Limits in Kanban: Improving Flow

Quick Definition:

WIP (Work-in-Progress) Limits are constraints on the number of work items that can be in a specific stage of a process at any given time. They are a core practice of Kanban.

WIP Limits

Why Use WIP Limits?

  • Reduce Multitasking: Encourages team members to focus on finishing tasks before starting new ones.
  • Identify Bottlenecks: When a stage reaches its WIP limit, it highlights a problem in the flow.
  • Improve Flow: By limiting the amount of work in the system, you can actually deliver work faster (Little’s Law).

Setting WIP Limits

Start with a limit that feels slightly uncomfortable and then adjust it based on the team’s performance and flow.
