An Integrated Customer-Focused Approach for Quality and Reliability

Quality and reliability for a product or process is defined and evaluated by the customer. Reliability is a time oriented quality characteristic. Time is a compound noise factor, and a reliable product/process must be robust against time. Similarly, a system has several quality characteristics which create impacts on customer satisfaction. This paper develops an integration of several quality and reliability methodologies such as robust design, quality engineering, quality function deployment (QFD), reliability engineering, and strategies for system integration. The objective is to develop a customer-focused approach for quality and reliability.
