Quality Control (QC) may be defined as a system that is used to maintain a desired level of quality in a product or service.
It is a systematic control of various factors that affect the quality of the product.
It depends on materials,tools,machines,type of labor,working conditions etc.
QC is a broad term,it involves inspection at particular stage but mere inspection does not mean QC.
As opposed to inspection,in quality control activity emphasis is placed on the quality future production.
Quality control aims at prevention of defects at the source, relies on effective feedback system and corrective action procedure.
Quality control uses inspection as a valuable tool.
According to Juran “Quality control is the regulatory process through which we measure actual quality performance, compare it with standards,and act on the difference”.
Another definition of quality control is from ANSI/ASQC standard (1978) quality control is defined as “The operational techniques and the activities which sustain a quality of product or service that will satisfy given needs; also the use of such techniques and activities”.
Alford and Beatty define QC as “In the broad sense,quality control is the mechanism by which products are made to measure up to specifications determined from customers, demands and transformed into sales engineering and manufacturing requirements,it is concerned with making things right rather than discovering and rejecting those made wrong”.
