More and more organizations seek to be recognized in the market for quality, efficiency, and quick response to changes. In this context, many paradigms and management methods emerge to address the external factors that make markets so volatile. Among several, Lean stands out as a management approach advocating practices and concepts of continuous improvement and waste reduction throughout the value chain, always aiming at satisfying those being served. Considered a way of thinking, it develops people by creating a culture where everyone is encouraged to use their thinking, knowledge, and acquired skills to solve problems and continuously improve. For the realization of this scientific article, the website of the non-profit organization, namely “Association A2000,” was analyzed. It was found that Lean implementation was only applied to some sectors of the organization due to a lack of qualified human resources for global implementation. It was also possible to observe the potential benefits of applying Lean management principles, even partially. However, there are difficulties in the organization regarding the implementation and continuity of its management. This is due to the lack of continuous professional training of human resources and the absence of a body/department with the necessary competencies for effective coordination of Lean management, thus jeopardizing the sustained continuity of the organization.
