The primary purpose of statistical process control (SPC) is to establish and maintain control of a process by detecting and reacting to special cause variation, determining when a process is not in control, and establishing control limits. SPC is used to improve the quality of a product and reduce waste and cost. While identifying specification limits is an important part of quality control, it is not a primary purpose of SPC. Specification limits refer to the range of acceptable values for a product or process, set by the customer or industry standards, that a company aims to meet or exceed.
