Kanban
Kanban is a visual signalling system that triggers production or replenishment only when downstream demand pulls it, limiting work-in-progress and overproduction. It is a core lean tool for running a pull system instead of pushing to a forecast.
Using cards, bins or digital signals, kanban lets a downstream step signal an upstream one to make or supply exactly what is needed, when needed. It caps inventory and work-in-progress, exposes bottlenecks, and smooths flow. Originating in manufacturing, the same pull-and-WIP-limit logic now also structures maintenance and knowledge work.
