How does quality control help firms improve production and operations?

"Putting Quality First Successful businesses recognize that quality and productivity must go hand in hand. Quality goods and services meet customer expectations by providing reliable performance. Defective products waste materials and time, increasing costs. Worse, poor quality causes customer dissatisfaction, which usually results in lost sales. A consumer measures quality by how well a product serves its purpose. From the manufacturer’s point of view, quality is the degree to which the product conforms to a set of predetermined standards. Quality control involves creating quality standards, producing goods that meet them, and measuring finished goods and services against them. It takes more than just inspecting goods at the end of the assembly line to ensure quality control, however. Quality control requires a company-wide dedication to managing and working in a way that builds excellence into every facet of operations. Dr. W. Edwards Deming, an American management consultant, was the first to say that quality control should be a company-wide goal. His ideas were adopted by the Japanese in the 1950s but largely ignored in the United States until the 1970s. Deming believed that quality control starts with top management, who must foster a company-wide culture dedicated to producing quality."
