Quality control (QC) is a procedure established to make sure that a manufactured product or service meets a set of quality criteria or the requirements of the client/ customer. QC is similar to quality assurance (QA). QA is defined as a procedure established to make sure that a product or service that is being developed meets specified standards.
To put an effective QC program into practice, one must first decide which standards the product/ service must meet. Then QC actions must be determined (e.g. the percentage of units to be tested). Next, real- world data must be gathered and problems identified (e.g. the percentage of units that failed) and the results reported to management personnel. The next step is to decide on some corrective measures (e.g. faulty units must be repaired/rejected). In case of too many faulty units the production process must be improved. Finally, it has to be checked whether the implemented modifications produced sastisfactory results.
