This article deals with the use of problem solving methodologies and how these positively affect the performance of KPI (Key Process Indicator) of organizations, clearly showing that those organizations that use these methodologies obtain better results over those who do not use them. With this work, what is sought is to question the myth, and put an end to the axiom that it was something taken for granted and confirm with statistical data the truth that methodologies work to improve the performance of organizations, as long as they are applied by teams trained in them. Leaving aside that the use of these methodologies is somewhat punctual to solve quality or production problems and that they must be used in the entire spectrum of organizations.
