This document summarizes and compares the contributions of three quality experts: Philip Crosby, W. Edwards Deming, and Joseph Juran. Crosby introduced the concept of zero defects and tracking the costs of non-conformance. Deming is known for his system of profound knowledge and plan-do-check-act cycle. He greatly influenced Japan's postwar economic recovery. Juran focused on fitness for use and balancing product features with deficiencies. While their approaches differed, all three emphasized the importance of management commitment, continuous improvement, and measurement in achieving high quality standards.
