An understanding of the differences in decisionmaking between incident-driven policing and community policing is essential when planning these changes. In incident-driven policing, decisions are made at the top of a hierarchical service; police managers are responsible for supervising and controlling uniformed officers whose conduct is regulated by the procedures and policies developed by senior management. In contrast, officers working in community policing work with the community to decide on the delivery of services; this independence requires a different style of agency organization. Data processing, specialized operational units, and research and planning are examined to illustrate some of the changes required under community policing.
