This study examines the MANAGER (Management and Accountability through Geographic Review) management model of the Arlington (Texas) Police Department. The study shows that MANAGER has the ability to incorporate the facilitative elements of a learning organization. The institutional tools, crime statistics, crime maps, hot spots, and crime analysis, organizational design through geographic policing, and the periodic local and central meetings are major elements of MANAGER in building a learning organization. A multi-dimensional survey of the APD's organizational performance is another issue of this research. The researcher measured the contribution of MANAGER to the APD's performance through a quasi-experimental time-series designs. The results indicate that the MANAGER has not made a significant contribution to the APD's organizational performance except in moderately controlling crime and clearing the cases, and significantly reducing firearm use. This case study adds value to the enormous Compstat descriptive studies by exploring the contributions of the MANAGER, a Compstat-like program, to the organizational performance of the APD.
