Primary inputs into the criminal justice system are the collection of criminal acts committed and the calls for services that they generate. The relationship between criminal justice system performance and system resources defines the system's capability. Management must heighten the criminal justice system's response in terms of both the type and effectiveness of services delivered. Resource allocation should be based on MAS, which covers system costs, productivity, personnel allocation, and workloads. MAS may be applied to impact studies, police resource allocation, and trial delay studies. The resource analysis planning process involves looking at the system's current state and asking questions about it, performing an analysis, and building on the results of that analysis for the development of strategies and recommendations of the most optimal alternative strategy to use. To effectively allocate resources, planners need to know about personnel, agencies' characteristics and hiring practices, workloads, equipment, facilities, and budgets. With adequate data and analytical procedures, criminal justice planners should be able to identify and define problems, know what resources are available to deal with the problems, and know how to allocate resources to solve the problems.
