• Batch Production• a group of items move through the
production process together, a stage at a time.
Batch Production Example
For example when a bakery bakes loaves of whole wheat bread, a large ball of whole wheat dough will be split into several loaves which will be spread out together on a large baking tray. The loaves on the tray will then together be cooked, wrapped and dispatched to shelves, before the bakery starts on a separate batch of, for example, crusty white bread. Note that each loaf is identical within a batch but that loaves can vary from batch to batch.
