The simplest and easiest to grasp definition of process manufacturing is that, once the output is produced, it cannot be distilled back to its basic components. In other words, once you put it together, you cannot take it apart. Think about it. Once you make a can of soda, you cannot return it back to its basic components such as carbonated water, citric acid, potassium benzoate, aspartame, and other ingredients. You cannot put the juice back into the orange. A car or computer, on the other hand, can be disassembled and the parts, to a large extent, can be returned to stock. Process manufacturing is common in the food, beverage, chemical, pharmaceutical, consumer packaged goods, and biotechnology industries. In process manufacturing, we talk about ingredients, not parts; formulas, not bill of materials; and bulk, not EA(each)'s. You may think that we are simply mincing words and terminology. But, as we will see later on this discussion, there is more than a subtle difference in their impact on manufacturing.
