Which manufacturing order quantity practice divides an order into smaller quantities after release to reduce lead time?

• A. Split lot
• B. Lot-for-lot
• C. Parallel production
• D. Batch splitting

Answer: (A)

Splitting a production order into smaller lots after release is a way to cut lead time by starting portions of the work sooner and delivering partial quantities earlier. When you divide the total quantity into smaller runs and release them in stages, each lot can begin processing as soon as its release occurs, rather than waiting for the entire order to be prepared. This overlap of work reduces the time from release to completion for parts of the order and can improve responsiveness to changing priorities or capacity constraints. That’s why this practice is described as split lot.

Lot-for-lot focuses on sizing orders to exactly meet demand in each period, which helps with inventory but doesn’t inherently shorten the total lead time by splitting the release. Parallel production uses multiple lines or paths to work on the same item at once, which reduces lead time through capacity, but it’s a different concept from dividing the order after release. Batch splitting isn’t a standard term in this context.
