Question: Who is Joseph Juran?
Answer:
Joseph M. Juran (December 24, 1904 – February 28, 2008) was one of the most influential figures in the history of quality management and is widely regarded as a foundational thinker in modern quality control and Total Quality Management (TQM).
Key Contributions and Legacy
-
Pareto Principle in quality
Juran popularized the idea that 80% of problems are caused by 20% of the causes — commonly called the Pareto Principle or 80/20 rule in quality contexts. He applied it to show that a small number of root causes usually account for the majority of defects, cost of poor quality, or customer complaints. - Juran Trilogy (his most famous framework)
- Quality Planning — designing products, processes, and services that meet customer needs
- Quality Control — monitoring and maintaining performance (using statistical methods)
- Quality Improvement — systematically reducing chronic problems and waste (breakthrough improvement)
-
“Quality is fitness for use”
Juran defined quality from the customer’s perspective rather than just meeting internal specifications. This customer-focused view was revolutionary in the mid-20th century. - Major works
- Quality Control Handbook (first edition 1951) — the “bible” of quality management for decades
- Juran on Planning for Quality (1988)
- Juran on Leadership for Quality (1989)
-
Role in Japan’s post-war quality revolution
Along with W. Edwards Deming, Juran was invited to Japan in the 1950s.
While Deming focused more on statistical process control and top-management responsibility, Juran emphasized practical project-by-project improvement, middle-management involvement, and the human/managerial side of quality.
His teachings strongly influenced companies such as Toyota, Sony, and many others that later became global quality leaders. - Juran Institute
In 1979 he founded the Juran Institute, which continues to provide training, consulting, and certification in quality management worldwide.
Quick Comparison: Juran vs. Deming

|---|---|---|
| Primary focus | Managerial + project-based improvement | Statistical methods + system thinking |
| Famous concept | Pareto Principle, Juran Trilogy | 14 Points, System of Profound Knowledge |
| Definition of quality | Fitness for use (customer view) | Predictable uniformity / loss function |
| Approach to improvement | Breakthrough projects | Continuous (kaizen-style) improvement |
