Limit Work in Progress (WIP)

Limiting Work in Progress (WIP) is a core Kanban practice that involves setting a cap on the number of work items that are in progress at any given time. The main objective of WIP limits is to prevent overloading the team, reduce multitasking, and enhance productivity by ensuring that team members focus on completing tasks rather than starting new ones. By imposing WIP limits, teams can minimize context switching, which often leads to decreased efficiency and increased errors. It encourages a flow-based approach where the emphasis is on moving work items through the entire process to completion before taking on new tasks. This practice helps in maintaining a steady flow of work and reduces the lead time for individual work items. Implementing WIP limits also aids in identifying bottlenecks within the workflow. When a particular stage reaches its WIP limit, it signals that the team needs to address any issues causing the slowdown before adding more work. This proactive approach enables teams to address problems promptly, leading to continual process improvement. In a practical sense, WIP limits are indicated on the Kanban board, usually at the top of each column representing a stage in the workflow. Team members are required to adhere to these limits, fostering discipline and a culture of completion. It also promotes collaboration as team members may assist each other to clear bottlenecks to allow new work to enter the system. For a Disciplined Agile Scrum Master, managing WIP is essential to balance demand against throughput and to ensure sustainable pace within the team. It aligns with agile principles of delivering value early and often by completing work items efficiently. Overall, limiting WIP enhances focus, quality, and predictability in the delivery process.
