Power of Kanban Metrics
9 likes1,329 views
This document discusses Kanban metrics and how they can help teams improve. It introduces four key Kanban metrics: the cumulative flow diagram, which shows work progress over time; the control chart, which tracks how lead time varies; lead time distribution, which shows how lead times are distributed; and the throughput chart, which tracks throughput over weeks. These metrics provide transparency into the workflow and can help teams identify areas for improvement through collaborative experimentation and kaizen.
