Quality pros have many names for these seven basic tools of quality, first emphasized by Kaoru Ishikawa, a professor of engineering at Tokyo University and the father of "quality circles. Therefore, all manufacturers and service providers out there constantly look for enhancing their product or the service quality. Plan: In this step of the quality control cycle, a business establishes the objectives and processes necessary to deliver results in accordance with the expected output (the target or goals).

Quality control consists of making a series of inspections and measurements to determine whether quality standards are being met. It is relative to the cost of the product i.e. quality is something which is consistent with the price of the product. Because of the numerous variables that enter into manufacturing, inspection is a never ending process. the notion of quality changes with times. 22 0 obj A close study of acceptance sampling technique would reveal that there is likelihood that a lot of satisfactory quality is rejected on the basis of sample result.
