Excellence models affect performance and help organizations achieve organizational excellence. Furthermore, organizational commitment is another concern of organizational excellence. The measurement of organizational commitment has become an important issue in TQM. In this respect, the extent to which employees are committed to what they are responsible for may directly influence the level of customer satisfaction with services and products. The main purpose of the study is to determine the relationship between an excellence model and organizational commitment. In order to achieve this goal, a survey that contains Meyer & Allen's Organizational Commitment scale and EFQM Criteria are applied to Turkish Quality Awards winners' employees in 2004. Data obtained in the study have been analyzed at the level of multivariate data analysis and the results show that the relationship between organizational commitment and EFQM Excellence Model was significant. Findings suggest that leadership, partnerships and resources, policy and strategy, affective commitment, processes, results, people development and involvement and continuance commitment are the determinants of the organizational commitment and EFQM Excellence Model respectively. Theoretical and practical implications of the findings are also discussed in the paper.
