Weber's understanding of bureaucracy, despite substantial qualification and revision, remains the dominant paradigm for the study of administration and formal organizations. We continue the process of revision by accepting his ideal-typical concepts of bureaucratic and patrimonial administration, but subject them to theoretical and historical reinterpretation and application. Our reading of historical change as it relates to bureaucracy leads us to question Weber's interpretations. His conceptualization of bureaucracy in terms of rational-legal-authority and formal rationality fails to take account of the existence and use of power within and outside of organizations, and of the persistence of patrimonial features. The use of power produces conflict and pathologies. When these serve the legitimate values and interests of participants and actors in the organizational environment, they can have benign consequences. The persistence of patrimonial features, rather than signalling the survival of dysfunctional atavisms, can promote administrative effectiveness by mitigating conflict and promoting organizational loyalty, discipline, and efficiency.
