Familiarity with quality loss reduction models and methods should be a priority for many U.S. manufacturers because costs of quality represent a significant percentage of total sales each year. This thesis provides an overview of quality costs, models, and control techniques based on selected readings. Costs of quality include failure, appraisal, and prevention costs. Focused attention should be given to prevention expenditures as a means to reduce quality failure and appraisal losses. However, U.S. manufacturers have only recently started to recognize this strategy. One model available to assist companies in establishing quality loss goals and strategic planning is Joseph Juran's Model of Quality Costs. This model recognizes the concepts of continuous quality improvement and zero losses as means for obtaining increased market share in today's global economy. Many quality tools and techniques are available to facilitate continuous improvement, but a very significant tool is control charts. Control charts enable companies to identify and reduce variability in production processes. Reduction of variability equates to reduction in the total costs of quality. This, in turn, represents increased profitability for the corporation. Quality assurance programs will enable companies to compete effectively in the fast-paced global market today and in the future.
