Toward a synthesis of criminal justice planning and evaluation

The traditional social engineering approach to planning is essentially an allocative planning based on the distribution of limited means among a number of established users. We need instead a transactive planning strategy based on substantive rationality. Such a strategy involves innovative planning which avoids narrow objectivism through a perspec‐tivistic approach. Evaluation is regarded as strategy for system learning. Both planning and evaluation are to be seen within a general systems framework. In this framework, evaluation is applied not only at the outcome stage but also at the stage of problem definition, in the various phases of policy development, and during policy implementation.
