What is Six Sigma and how is it related to Total Quality Management?

Dr. Wole Akpose explains it all here.


The contributions of Bill Smith, Walter A. Shewart, and W. Edwards Deming are discussed.


Here's an important point by W. Edwards Deming:

1. When people and organizations focus primarily on quality as defined by

Quality = (Results of work efforts)/(Total costs)

quality tends to increase and costs fall over time

2. When people and organizations focus primarily on costs, costs tend to rise and quality decline over time.
