A process specification is a document that outlines the steps necessary to produce a particular product. You can use it to define the manufacturing process, assembly process, or any other type of production process. A process specification aims to ensure that all products are produced according to the same standards. This type of document is often used in quality control and can be used to audit the manufacturing process. A process specification typically includes a list of all materials and supplies needed and detailed instructions on how to assemble or produce the product. A process specification may also include inspection and testing procedures in some cases.
