Definition Quality QC QA

The definition of quality assurance and quality control has been re-framed and re-worded by different quality experts from time to time. It also varies from industry to industry. Let us take a look at some of these definitions to understand the concept.

As per American National Standard (ANSI/ASQC A8402-1994), quality control refers to all the planned and systematic activities implemented within the quality system, and demonstrated as needed, to provide adequate confidence that an entity will fulfil requirements for quality.

American Society for Quality (ASQ) defines assurance of quality as the planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled.

From the above definition of quality control, we can say that quality guarantee or assurance is the set of procedures developed and activities done before the product or service is manufactured or delivered to assure of good quality to the customers. This is a proactive approach.

Definition Of Quality Control

After having understood the definition of quality assurance , lets see what the definition of quality control is. Juran says Quality control is a universal managerial process for conducting operations so as to provide stability – to prevent adverse change and to maintain the status quo.

As per American Society for Quality, quality control is the observation techniques and activities used to fulfill requirements for quality.

From the above two definitions, we can say that quality control is the set of activities performed to ensure that the products or services meet the requirements as defined during the earlier process  for assurance of quality. These activities are done during the manufacturing process and once the product is manufactured.
