Cumulative lead time refers to the total time taken to complete a series of linked tasks or processes in a supply chain, particularly when it involves multiple stages from the initial order to final delivery. It essentially measures the longest total duration necessary to fulfill an order, accounting for each stage in the production and delivery process. This concept allows businesses to anticipate how long it will take to complete orders, helping in planning and resource allocation.

The other options describe different aspects of supply chain operations but do not define cumulative lead time accurately. For example, while the time taken to complete all orders in production might relate to overall production efficiency, it doesn’t capture the essence of lead time, which is about the sequence and timing of activities. Similarly, total time a product is held in inventory or average shipping time to customers reflects inventory management and distribution efficiency rather than the broader concept of cumulative lead time involving all stages of the supply chain.
