The business terms push and pull originated in the
marketingand advertisingworld,Fact|date=April 2007 but are also applicable in the world of electronic content and supply chainmanagement. The push/pull relationship is that between a product or piece of information and who is moving it. A customer "pulls" things towards themselves, while a producer "pushes" things toward customers.
In a "push" system the consumer does not request the product to be developed; it is "pushed at" the end-user by promotion. An example of this is a perfume product. Women do not request to smell a fragrance they never smelled before; it is simply "pushed" at them, through the right advertisement.
*Applied to that portion of the supply chain where demand uncertainty is relatively small
*Production & distribution decisions are based on long term forecasts
*Based on past orders received from retailer’s warehouse (may lead to
*Inability to meet changing demand patterns
*Large and variable production batches
*Unacceptable service levels
*Excessive inventories due to the need for large safety stocks
In a "pull" system the consumer requests the product and "pulls" it through the delivery channel. An example of this is the car manufacturing company
Ford Australia. Ford Australia only produces cars when they have been ordered by the customers.

With a push-based supply chain, products are pushed through the channel, from the production side up to the retailer. The manufacturer sets production at a level in accord with historical ordering patterns from retailers. It takes longer for a push-based supply chain to respond to changes in demand, which can result in overstocking or bottlenecks and delays (the
bullwhip effect), unacceptable service levels and product obsolescence.
In a pull-based supply chain, procurement, production and distribution are demand driven so that they are coordinated with actual customer orders, rather than forecast demand.
A supply chain is almost always a combination of both push and pull, where the interface between the push-based stages and the pull-based stages is known as the push–pull boundary.

Inventory levels of individual components are determined by forecasting general demand, but final assembly is in response to a specific customer request. The push-pull boundary would then be at the beginning of the assembly line.
