Manufacturing plants or factories take raw material inputs and add value through a sequence of unit processes before shipping a product. Now, this process must follow a recipe. There are a series of instructions for products such as cars; in those instructions, a list of parameter values, specific temperature for iron melting, specific pressure for mold casting… and the list goes on.
These factories, for instance, those in the automotive space, do all of the quality inspections, in-line and end-of-line, to ensure the cars are in good shape; if not, they are scrapped or reworked, becoming lost capacity and effort for the factories. Employees hired to keep these processes in check can make mistakes; thus, such factories also rely on software to evaluate their experiences, change parameters if needed and ensure that the car reaches the end-of-line as high quality as possible.
