Abstract:

The Six Sigma Quality discipline provides a plethora of problem solving and improvement tools. Judicious use of these tools requires careful thought and planning. While at times it pays to use Quality Six Sigma tools to define, measure, analyze and improve systems, sometimes use of the tools can waste a good deal of time and effort and not add significant value. This paper is based on the premise that it is most expedient to utilize experience and domain knowledge to focus on the problem at hand, then apply Six Sigma or other tools as necessary to enhance the problem-solving process. The amount of rigor in analysis and modeling should be tempered by the level of accuracy needed for confident operational decision-making.
