Quality Control (QC) is a reactive approach concentrating on identifying and correcting defects in the final product. It is often performed by a specific department or team responsible for inspecting, testing, and sampling products. QC activities involve testing raw materials, conducting inspections during production, and performing final product testing. The main objective of QC is to detect and address deviations from quality standards, to ensure that the final products meet required specifications. In the context of a PBM company, QC would involve testing the texture, flavour, nutritional content, and other attributes of the final products, as well as inspecting incoming raw materials for quality.
