Keys to success for Six Sigma

This paper describes how the characteristics of the Six Sigma methodology are able, if properly used, to bring new light to process comprehension and problem solving. Each of the 5 phases in which Six Sigma is structured (DMAIC) sets few milestones that indicate the walk to do. The way these milestones are defined, the ability of the people to understand the contest, the proper effort in order to ga in the goal are issues that may influence the final results. Correct use (right one for the right information) of the tools, the rigour of the method, the step-by- step approach and a strict time management on projects are surely the basis for a success. The different examples provided in this pages, show what is the most important aspect of the methodology: its possible application to everything we may define as process. Key issues therefore are: extensive application of the methodology to all the processes, great flexibility and customization, the im provement opportunities identification and selection; results evaluation and validation.
