In sports, the goal is to win. The players selected, along with the strategy used on the field, are the primary weapons of any team. Six Sigma promotes a process approach, ie. identifies errors, selects the most important ones by priority and acts on them in a targeted manner. The Pareto (ABC) diagram is a graphical method for analyzing phenomena in which the magnitudes/phenomena or errors and their causes are ranked in descending order. The purpose of this paper is to encourage thinking about how applicable the concept of Six Sigma and the Pareto diagram is in basketball and what makes it so attractive to many successful basketball players, coaches and clubs in the world.
