Compare push based supply hain and pull based supply chain?

Answer 1

The business terms push and pull originated in the marketing and selling world. but are also applicable in the world of electronic content and supply chain management. 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. 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, 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. An example of this would be Dell's build to order supply chain. 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.
