Quality is one of the toughest concepts to understand. Maybe "Quality"is treated on lines of "Importance" or "Logic".
Philip Crosby said, "Zero Defects". Many say, "Customer Satisfaction".
Edwards Deming was the first guru on Quality. He was mainly interested in statistical quality analysis and quality improvement. He referred to methods of Shewart in statistical analysis.

Armand Feigenbaum, the third American Quality guru stressed on Total Quality Management. He talked about problem solving abilities, conflict resolution, standardization. He stressed that everyone has a responsibility on Quality.
Genichi Taguchi, the Japanese Quality guru was interested in quality of products and made formulas for better products. He said cost can be brought down by quality of products.
Kaoru Ishikawa, the Japanese Quality guru pioneered the cause-effect diagrams and was instrumental in the Quality circle idea.
