Quality in various contexts, such as manufacturing, services, or management, refers to the degree of excellence or superiority of a product, service, or process. It encompasses principles like continuous improvement, customer focus, and data-driven decision-making. Pioneers like W. Edwards Deming and Joseph Juran have significantly contributed to the development of quality management principles. The importance of quality lies in its ability to enhance customer satisfaction, reduce costs, increase efficiency, and ultimately, contribute to the long-term success and competitiveness of organizations in today's global marketplace.
