Actions performed on the combined ingredients vary widely and include curing, baking, pressurizing, pasteurizing, and chemically catalyzing or reacting. Once a product has been made through process manufacturing and reaches its final form, it typically cannot be broken back down into its constituents.
Key industries that rely on process manufacturing include consumer packaged goods (CPG), food and beverage (F&B), and fine and specialty chemicals.
Goods produced through process manufacturing are made in batches – finite quantities usually measured in mass or volume – or via continuous-flow processing. In batch processing, the sequence of process operations for a particular product is performed on a batch-by-batch basis. In continuous-flow processing, units of the materials/intermediate products move from one processing step to the next with no breaks, such that each processing step is performed continuingly, proceeding from one unit to the next.
A process manufacturing industry is often required to track processing parameters and testing results for each batch, or at set intervals based on volume or mass in continuous-flow processing. This requirement may be handled through paper records, but process industries are adopting electronic batch records (eBRs) for manufacturing more and more to streamline recordkeeping.
Importantly, a majority of process manufacturers also package their goods, which means they must manage a dual value chain: a batch or continuous-flow process for the primary product and a discrete manufacturing operation for filling, packaging, and palletizing. In a significant subset of process industries, such as tire and battery production, discrete manufacturing steps extend beyond packaging and are integral to the creation of the finished product. Both these integral steps and discrete packaging steps necessitate manufacturing operations management (MOM) software for process industries that is designed to manage the operational characteristics of both discrete and process manufacturing, which differ considerably.
