The business terms push and pull originated in logistics and supply chain management, but are also widely used in marketing. Wal-Mart is an example of a company that uses the push vs. pull strategy. A push–pull system in business describes the movement of a product or information between two subjects. On markets the consumers usually "pull" the goods or information they demand for their needs, while the offerers or suppliers "push" them toward the consumers. In logistics chains or supply chains the stages are operating normally both in push- and pull-manner. Push production is based on forecast demand and pull production is based on actual or consumed demand. The interface between these stages is called the push–pull boundary or decoupling point.
