Deming vs Juran vs Crosby
Three commonly cited quality management theorists quoted on the exam are: W. Edwards Deming, Joseph Juran, and Philip Crosby.
Deming was an American statistician, professor, author, lecturer, and consultant.
He believed that organizations can increase quality and reduce costs by practicing continuous process improvement and by thinking of manufacturing as a system, not as bits and pieces.
Juran was a 20th century management consultant and evangelist for quality and quality management.
He applied the Pareto principle to quality issues (80% of the problems are caused by 20% of the causes) and also developed “Juran’s Trilogy”: quality planning, quality control, and quality improvement.
Crosby was an American businessman and author. Crosby’s response to the quality crisis was the principle of Doing It Right the First Time (DIRFT).
He applied four major principles:
- The definition of quality is conformance to requirements
- The system of quality is prevention
- The performance standard is zero defects
- The measurement of quality is the price of non-conformance
