control (Chapter 11), and feedback adjustment techniques (Chapter 12). Advantages of uses of statistical quality control, It enables us find out whether a specified quality standard is being maintained or not, without inspecting each and every item produced. Evaluations obtained by these methods assist in maintaining desired result by using past history to predict capabilities or trends. Thus SQC is meant to stop wastage by, finding out the quality of the product during the course of production. Course Hero is not sponsored or endorsed by any college or university. If the, specified quality standard is not being maintained the cause of it has to be ascertained and set, right before and further production takes place. Statistical Quality Control (SQC). If the production, process is not in control and defective items have been produced it is a dead loss.
