Policy analysis are one of two techniques used by social science researchers to determine if current policies are effective and whether existing strategies and policies should be continued, or if they should explore new policies and strategies. Policy analysis looks at governmental behavior, where it is as much interested in the actual actions of government as in the inactivity of government and can be conducted by researchers from various fields such as criminal justice., Hagan (2014). Policy analysis also studies the policies that were drafted and implemented by the government, those which may or may not have been proposed, and those that were never implemented by the government, Hagan (2014).
