If an item is produced in large quantities, this is usually called mass production. The item produced is called product, and it is usually made in a factory. The items produced will all be the same type. The process of making large quantities will usually require the use of standardized products or product groups.
Today, machines are often used to mass produce such items. Using division of labour, a greater number of items can be produced. Adam Smith used the example of a needle: With division of labour, it is possible to produce more needles in the same time. Frederick Winslow Taylor, the father of Taylorism also used the division of labour: he wanted to divide the tasks into planning tasks, and execution.
