The Quality Revolution
• • •
Started in Japan by Deming, Juran, and Ishikawa during 1940s In 1950s, Deming introduced statistical quality control to Japanese engineers Statistical quality control (SQC) is a discipline based on measurement and statistics
– SQC methods use seven basic quality management tool • Pareto analysis, Trend Chart, Flow chart, Histogram, Scatter diagram, Control chart, Cause and effect diagram
•
“Lean principle” was developed by Taiichi Ohno of Toyota
“A systematic approach to identifying and eliminating waste through continuous improvement, flowing the product at the pull of the customer in pursuit of perfection.”
