Which of the following statements would generally be considered correct? a) Job shops normally compete by offering a lower price than their competitors. b) Batch processing produces a more standard range of products than continuous flow processes. c) Production runs are shorter for continuous flow systems than for mass production systems. d) Job shops can produce a larger range of products than project systems. e) Labour costs are higher in a job shop operation than in most other processes.
