What is meant by 'process batch' in manufacturing?

1. The total number of products produced in one day

2. The quantity of output to be completed before changing setups

3. The maximum capacity of the equipment

4. The volume of raw materials required for production

The correct answer is: The quantity of output to be completed before changing setups

In manufacturing, the term 'process batch' refers specifically to the quantity of output that is produced before there is a need to change setups. Setting up machinery or equipment for a new production run can be time-consuming and costly. Therefore, manufacturers often aim to produce a certain amount of product—this specific quantity is known as the process batch. By defining and adhering to a process batch size, companies can optimize their production efficiency. It minimizes the frequency of changeovers, which can disrupt the flow of production and increase idle time. Furthermore, by producing in larger batches, manufacturers can take advantage of economies of scale, reducing per-unit costs. The other choices reflect different manufacturing concepts but do not define the process batch. The total number of products produced in one day refers to overall daily output, not the quantity linked to a specific setup. Maximum capacity of equipment focuses on the highest level of output that can be produced under ideal conditions, which does not relate to changing setups. The volume of raw materials required for production is concerned with input rather than the operational mechanics of processing existing materials into finished goods.
