Quality always has been an integral part of virtually all products and services. It is continuously meeting exceeding customer and supplier needs, requirements and expectations in all aspects. However, our awareness of its importance and the introduction of formal methods for quality control and improvement have been an evolutionary development. This article present Core concepts of contemporary quality management Quality Control techniques Control Chart to measure, analyze and control quality by continuously monitoring, controlling and managing process maintaining sampling to continuously Improvable targets by continuously producing and offering services within low and lower Percentage Defectives in meeting exceeding customer and supplier needs, requirements and expectations. Sampling, Sample size and sample numbers of Proportion of population covered with sampling Rational sub group, are two basic for quality monitoring and control to manage quality of products as well as services within Continuously improving tolerable number and/or Percentage Defectives.
