During our Six Sigma studies we will be examine some important quality paradigms from such quality gurus as: Deming. Juran, Crosby, Ishikawa and Taguchi.
Dr. W. Edwards Deming (October 14, 1900 – December 20, 1993) was an American engineer, statistician, professor, author, lecturer, and management consultant born in Sioux City, Iowa. Deming completed his BS in Electrical Engineering, followed by a Master’s Degree and PhD from Yale University.
Dr. W. Edwards Deming was instrumental in the rise of Japan as a manufacturing power and in the invention of theories for “Total Quality Management” or TQM
Deming’s Philosophy is comprised of some important tenets:
- The use of Statistical Process Control to identify special and common cause variations. Special because variations are erratic and unpredictable, but common because variations are inherent in the system. Ultimately, our objective should be to eliminate special cause variations and decrease common cause variations to improve the quality of goods produced.
- Quality depends on the policies of management and if management creates appropriate conditions and motivations for workers to improve quality, then every worker will contribute to a better quality product. His “Theory of Profound Knowledge” talks about how management should create conditions in which every worker contributes to quality improvement.
- Use the _______________________________________________ (PDCA) model to improve quality.
