A fundamental element for the sustainable long-term success of any organization is an effective improvement program. Six sigma is a powerful improvement methodology that, if correctly implemented, can be an important component of a management system aimed at sustainability. However, a successful implementation of six sigma is not an easy task, in this paper we share our experience after five years of extensive six sigma training and consulting in Spain and South America. We are responsible for a Black Belt open enrollment training and deployment course offered by the Technical University of Catalonia (UPC) in Barcelona, San Sebastian and Santiago de Chile. In addition to presenting some of the lessons learned throughout this experience, we comment on two aspects of the use of the methodology that we believe may affect the future of six sigma: the extent to which statistics must be included in a Black Belt training course and the amount of guidance that needs to be built into both the tools to be used and the DMAIC (define, measure, analyze, improve, control) methodology, in order to obtain the maximum possible benefit with the least possible effort from the six sigma process. We finish with some conclusions.
