Business excellence initiatives help organizations develop and increase management capabilities in order to achieve high performance and greater competitiveness, and management commitment to implement excellence models and self-assessment based on them is an important initial stage of the organizational excellence process. The present applied research seeks to identify and classify all its components in the implementation of business excellence models by examining the concept of management commitment. In this regard, by reviewing the research literature and conducting semi-structured interviews with experts, 92 components that form the concept of management commitment were identified and counted, and validated using a questionnaire and their importance was assessed. Based on the implementation of exploratory factor analysis, the components of management commitment were categorized into 4 main factors: ownership of organizational excellence, improvement programs, membership in self-assessment teams and creating integration, and creating and developing a culture of excellence. By identifying and categorizing the components of management commitment, this research lays the groundwork for creating a broader understanding and awareness for managers of their roles and responsibilities in implementing excellence models and increasing the effectiveness of the organizational excellence process.
