Purpose: Quality management has become an integral part of management reforms in public sector organizations. Drawing on a new institutionalist perspective, this study aims to investigate the relation of management reforms and organizational performance in the context of higher education. Design/methodology/approach: The authors analyse the interaction between isomorphic conformity in quality management adoption, organizational learning and quality improvement and, in so doing, address the central theoretical question of what effects isomorphic conformity has on organizational performance. Empirically, the study draws on survey data from quality managers at public higher education institutions in Germany. Methodically, it applies confirmatory factor analysis and structural equation modelling. Findings: The results suggest that mimetic isomorphism is surprisingly compatible with processes of organizational learning, and thus, does not inevitably compromise organizational development. Originality/value By presenting these findings, the authors contribute to the controversial theoretical debate concerning the effects of isomorphism and to the ongoing discussion regarding the organizational impact of quality management in higher education.
