Can we have percentage completion at Kanban Board?
The Kanban Board In Kanban, the emphasis is on visualizing work and workflow rather than estimating percentage completion of tasks directly. Kanban boards typically represent work items as cards moving through various stages of a process, from "To Do" to "Done". Here's how completion is typically inferred in a Kanban board:
Visual Cues: The position of a card on the Kanban board provides a visual indication of its status within the workflow. For example, if a card is in the "Done" column, it indicates that the task or work item associated with that card is completed.
Work in Progress (WIP) Limits: Kanban boards often include WIP limits for each stage or column. These limits help control the amount of work in progress at any given time. When a column reaches its WIP limit, it suggests that additional work cannot enter that stage until some of the existing work moves forward (indicating completion).
Cycle Time and Lead Time: Metrics like cycle time (time taken to complete one item from start to finish) and lead time (total time taken from request to completion) provide insights into the efficiency and pace of work completion. These metrics are more quantitative measures of completion rather than percentage-based.
Cumulative Flow Diagram : This is a tool often used in Kanban to track the flow of work items over time across different stages of the process. It provides a snapshot of work items entering and leaving each stage, which can indirectly indicate completion rates and overall process efficiency.
Why Percentage Completion is Not Typically Used in Kanban?
Focus on Flow: Kanban focuses on continuously flowing work through the system rather than categorizing work into completed or incomplete based on percentages.
Variability : Tasks in Kanban can vary widely in size and complexity, making it challenging to accurately estimate percentage completion for each task.
Continuous Improvement : Instead of estimating completion percentages, Kanban encourages teams to focus on continuous improvement of flow and delivery times.
Conclusion : In summary, while Kanban boards provide clear visibility into the status of work items and their progression through stages, they do not typically infer percentage completion directly. Instead, Kanban emphasizes continuous flow, managing work in progress, and improving overall process efficiency.
