A kanban is essentially a visual scheduling system that allows for the rapid adjustment of production in response to demand shifts. This method of scheduling based on demand is known as a "pull" based system. 

The utility of kanban is to signal the depletion of material at any stage of the production process and need for replenishment. By building/replenishing only based on demand of the next station, waste can be minimized as there will be a lack of build up of semi-finished materials that leads to wasted wait time between stations.

Lean Manufacturing Principles hypothesizes that demand-driven systems lead to faster turnarounds in production and lower inventory levels, which reduces waste in both time and materials and processing time.
