Batch processes - suit products with moderate output. Some standardisation and modular designs permit some economies of scale and lower unit costs. Flexible process layouts enable variations in volume and specification without prohibitive cost problems. An order for 300 units may be satisfied as easily as 6,500. Minor changes in specification could be acommodated.
Standardisation covers materials, process stages and routinisation of skills.
A stoppage of the line or process means that the output the line could produce is lost enirely.
