Snippet from Wikipedia: Kanban (development)

Kanban (Japanese 看板, signboard or billboard) is a lean method to manage and improve work across human systems. This approach aims to manage work by balancing demands with available capacity, and by improving the handling of system-level bottlenecks.

Work items are visualized to give participants a view of progress and process, from start to finish—usually via a Kanban board. Work is pulled as capacity permits, rather than work being pushed into the process when requested.

In knowledge work and in software development, the aim is to provide a visual process management system which aids decision-making about what, when, and how much to produce. The underlying Kanban method originated in lean manufacturing, which was inspired by the Toyota Production System. It has its origin in the late 1940s when the Toyota automotive company implemented a production system called just-in-time; which had the objective of producing according to customer demand and identifying possible material shortages within the production line. But it was not until Microsoft engineer David J. Anderson noted how this method devised by Toyota could become a process applicable to any type of company that needs organization.

Kanban is commonly used in software development in combination with other methods and frameworks such as Scrum.
