The preconditions for successful evaluation: Is there an ideal paradigm?

The dominant paradigm in evaluation research is undergoing serious challenge. This article explores the ideal role of evaluation in decisionmaking, the methodologies for conducting evaluations, the congruence between evaluation methodology and actual organizational behavior, and the relationship between evaluators and program managers. We conclude that although there are serious disparities between the ideal and the actual in each of these four areas, and especially in the congruence between evaluation methodology and organizational behavior, there is not likely to be a change in the dominant paradigm because it is difficult for practitioners to use the language and values of new organizational perspectives.
