This document provides an introduction to Kanban, a lean methodology for managing workflow. It describes Kanban's focus on visualizing and limiting work in progress to improve flow. The key aspects covered include: - Using a board to visualize workflow between stages like analysis, development, testing etc. - Tracking work in progress and completed items to understand flow. - Using queues, limits and blockers to manage flow through the system. - Highlighting the benefits of this approach over practices like overtime to continuously deliver value.
