Pull Systems are another very important Lean Manufacturing concept. Traditional manufacturing used the “push”
concept, making large batches of product and “pushing”
them to each downstream operation whether they are ready for
them or not.
Push systems also often have products produced that are not
Ideal Pull Systems start at the opposite end, the customer,
and once the customer signals an order, that last process
signals to the upstream process to produce product. Each upstream
process receives the signal (order) from the downstream process
that it needs product, all the way back to the supplier of
Idea pull systems do not produce to inventory. Lean manufacturing concepts teach why inventory is one of the largest wastes
in a company. Inventory costs money to purchase which raises
the working capital necessary to run a business. The excess
working capital necessary forces the company to either use
its cash for inventory or raises borrowing amounts. Excess
inventory often results in inefficient operations from having
it in the way. Inventory often becomes obsolete having to
be “written off” or sold at a loss or a lower
It is imperative that companies embarking on a pull system
understand and employ lean manufacturing concepts as they
apply to their manufacturing process. Concepts such as “kanban”
often need to be utilized to keep the flow in a pull system.
If a company employs a pull system prior to being ready for
the change, it will incur additional costs from down time
and higher per unit costs.
Our Lean Manufacturing on line course teaches the pull system
and how it applies in the manufacturing setting. The course
includes all of the lean concepts because they must all be
understood to apply lean effectively.
