Problem-oriented policing (POP), coined by University of Wisconsin–Madison professor Herman Goldstein, is a policing strategy that involves the identification and analysis of specific crime and disorder problems, in order to develop effective response strategies. For years, police focused on the “means” of policing rather than its “ends”, according to Goldstein. Goldstein (1979) called to replace what he termed the reactive, incident-driven “standard model of policing”. This approach requires police to be proactive in identifying underlying problems which can be targeted to reduce crime and disorder at their roots. Goldstein’s view emphasized a paradigm shift in criminal law, but also in civil statutes and the use of municipal and community resources. Goldstein’s 1979 model was expanded in 1987 by John E. Eck and William Spelman into the SARA model for problem solving.

This strategy places more emphasis on research and analysis as well as crime prevention and the engagement of public and private organizations in the reduction of community problems.
