The total time required for a unit to pass through the entire production process.

• A. Lead Time
• B. Throughput Time
• C. Processing Time
• D. Elapsed Time

Answer: (B)

Throughput time is the total span a unit experiences as it moves through the production system, from the moment it enters production to the moment it leaves as a finished product. It includes all stages, transfers, and any delays between operations, capturing the full clock time of the production process. This makes it the best fit for the total time a unit passes through the entire production flow, not just the time spent actively processing. Processing time is only the active work time on the unit, excluding waiting or idle periods. Lead time covers the entire horizon from customer order to delivery, which includes activities outside the production floor. Elapsed time is not a precise standard term for this context, whereas throughput time specifically denotes the complete production-cycle duration.
