Abstract
The development of quality systems has evolved from many principles and techniques. These principles and techniques include kanban , hashin-kanri , kaizen , quality control circles, quality function deployment, just in time, Deming's 14 points, etc. In reality, these principles and techniques have been successful in achieving improvement in the areas of design, variation reduction, team building, customer satisfaction, leadership, prevention, process improvement etc. The role of quality systems using statistics is vital for the analysis of the variation that exists in every process and decisions are made for improvement on that basis. It is also important to understand that a set of standards (e.g. ISO 9000) has been used for the quality assurance of a system in order to offer customers quality in products and services. This paper discusses critically the understanding of quality systems, and testing standards, in order to provide an integrated approach to the quality system for the benefit of the organizations.
