| A Pull System is a type
of production system used in Lean
Production in which production
is triggered by demand. Usually when an
item, or small batch of items, is 'consumed'
a kanban
triggers replenishment. Kanbans 'pull' product
through each stage of production.
This differs from a traditional 'push'
system where production is scheduled to
meet anticipated demand, and then 'pushed'
through production as quickly as possible.
Push systems usually generate too much inventory
and items that should have priority are
often delayed behind items that are less
urgent.
