The document compares and contrasts pull and push manufacturing systems. A pull system bases production on actual daily demand, with information flowing from the market to management. A push system bases production on a projected production plan, with information flowing from management to the market. Some advantages of a pull system are limited inventory, being customer centric, and improved cash flow. Some advantages of a push system are high inventory and making products to stock based on forecasts. Disadvantages of a pull system include needing balanced systems and setup times impacting throughput. Disadvantages of a push system include potentially generating scrap before errors are found and requiring large, complex databases and diligent product flow maintenance.
