General Description

Six Sigma, which began as a methodology for improvement, became a strategy for success. Corporations reported huge savings. Thus, Six Sigma was standardized as statistical and fact driven five phase methodology. Statistics, which is supposed to help in the analysis of data for drawing conclusions when uncertain, became a main attraction for some and distraction for others. For many of us, statistics became a real pain. The excessive focus on statistics led to confusion, waste in its implementation, and impediment to realizing benefits. 

Stat Free Six Sigma has been written to minimize the use of statistics, and to incorporate instead statistical thinking. Authors using their experience of about 30 years combined, have simplified Six Sigma by focusing on its intent to achieve quick breakthrough improvement by focusing on non-statistical powerful and proven tools. Where statistics is required, it has been converted into simplified arithmetic. 

Six Sigma professionals, novices and practitioners equally alike, will find the Stat Free Six Sigma (SFSS) book a straight book on Six Sigma easy to follow, and be able to realize great results through innovative application.
