How is "lead time demand" defined?

"Lead time demand" is defined as the expected product demand during the lead time period. This concept is crucial in inventory management and material planning, as it helps businesses understand how much product will be required while waiting for new inventory to arrive.

Essentially, lead time refers to the duration from when an order is placed until it is received and ready for use. During this span, businesses continue to sell products, and estimating the demand expected in this timeframe allows for effective inventory control. By calculating lead time demand accurately, organizations can minimize the risk of stockouts and ensure they have enough inventory to meet customer needs during the lead time.

The other options present different aspects of inventory and order management but do not capture the definition of lead time demand. One option discusses order quantity, another addresses the execution time of orders, while the last option focuses on demand in a specific sales period, which does not specifically relate to the lead time concept. Therefore, option A is the most accurate definition within the context of supply chain management.
