Which definition describes batch production?

• A. the making of a single, unique product
• B. a manufacturing operation that produces goods in large batches in standard lot sizes
• C. production of goods in large numbers through the use of machinery and assembly lines
• D. Delivered when needed so no warehousing to store parts

Answer: (B)

Batch production means grouping items into a batch and making a set number of units before moving on to the next batch. This approach sits between making a single bespoke item and continuous mass production, offering a balance of efficiency and flexibility. It works best when you need multiple identical items but not at the very high volumes of continuous flow, and it uses standard lot sizes so setups can be reused within each batch. The description that fits this idea is producing goods in large batches in standard lot sizes. The other descriptions describe different methods: making a single unique product is job production, using machinery and assembly lines to produce in very high volumes is mass or flow production, and delivering goods just in time with no warehousing refers to inventory strategy rather than the production method.
