Pull System

Production triggered by actual downstream consumption rather than forecasts — work is pulled by demand.

In a pull system, nothing is produced until a downstream process signals it is needed; work is "pulled" through the value stream by real consumption. This prevents the overproduction that plagues forecast-driven push systems.

Pull is typically implemented with kanban signals and supermarkets, and is a core enabler of Just-in-Time. By capping WIP it directly controls lead time.

Production driven by forecasts and schedules, pushing work downstream regardless of actual demand.
Kanban
A visual signaling system that triggers production or replenishment based on actual consumption rather than forecasts.
Just-in-Time
Producing and delivering exactly what is needed, when it is needed, in the amount needed.
Supermarket
A controlled inventory store of standard quantities that a downstream process pulls from and upstream replenishes.
CONWIP
A pull system that caps the total work-in-process in a line, releasing new work only as finished work exits.
