What do push systems primarily rely on to produce goods?

Push systems primarily rely on sales forecasts to produce goods because these systems are designed to manufacture products based on anticipated customer demand rather than actual customer orders. In a push system, production planning is driven by forecasts of what the company expects customers to buy. This means that goods are produced and "pushed" through the supply chain toward the market, with inventory building up in anticipation of future sales.

This reliance on sales forecasts allows a company to plan production schedules, manage inventory levels, and optimize resource allocation before actual demand materializes. It is important to note that if the forecasts are inaccurate, it can lead to overproduction or stockouts, affecting efficiency and customer satisfaction. Thus, understanding the intricacies of how push systems work with sales forecasts is crucial for managing operations effectively.
