Push versus Pull Supply Chain Management

Pull Supply Chain Systems

A pull system in a supply chain refers to a replenishment model that relies on signals from further down the supply chain that inventory need to be replaced. These signals are not order from the next level as orders reflect batches across time (or order batches). Various types of signals can be used with the most effective being signals derived from checkout counters. These signals should not be mistaken for demand. A product can be demanded, but not in stock yields no replenishment signal.
