Quality – The composite of all the characteristics, including performance, of an item, product or service that bear on its ability to satisfy stated or implied needs. In a contractual environment, needs are specified, whereas, in other environments, implied needs should be identified and defined. In many instances, needs can change with time; this implies periodic revision of requirements for quality. Needs are usually translated into characteristics with specified criteria. Quality is sometimes referred to as “fitness for use”, “customer satisfaction”, or “conformance to the requirements.”
