The Power of Kanban for Agile Project Execution
The Kanban methodology (originating at Toyota in the late 1940s) visualizes work in progress to eliminate bottlenecks and optimize throughput. By limiting WIP (Work In Progress) and maintaining clear visibility over tasks from backlog to completion, software developers and entrepreneurs execute sprints with higher focus.
