Final answer:
The incorrect characteristic of batch processing is that 'batches are produced in accordance with detailed customer specifications'. The correct answer is option b.
Step-by-step explanation:
The characteristic of batch processing that does not belong in the given list is b. batches are produced in accordance with detailed customer specifications. Batch processing typically refers to a method of manufacturing where items within a batch are similar and processed in a group.
This method is often used to replenish inventory levels, with batch production occurring in response to demand. Each batch goes through one stage of the production process before moving on to the next; thus, setting up and retooling is necessary when the batch changes.
This is different from customized production, which is often done on an individual basis and according to specific customer specifications. By contrast, batch processing aims for efficiency and tends to be less focused on individual customization.
