Which supply chain planning function determines how much product is needed to satisfy all customer demands?

The function that determines how much product is needed to satisfy all customer demands is demand planning. This process involves forecasting customer demand for products over a specific period to ensure that the right amount of inventory is available. By analyzing historical sales data, market trends, and customer behavior, demand planning helps organizations align their production, inventory management, and supply chain operations with actual market needs.

In this context, demand planning is essential for achieving efficiency and minimizing costs, as it allows companies to avoid both overstock situations and stockouts. By accurately estimating the amount of product required, organizations can make informed decisions about procurement, production schedules, and other supply chain activities.
