This article focuses on the instrumental utilization of evaluation findings to assist in the development of program policy, including a brief review of some of the literature in this area. The context from which examples are drawn is an innovative human service program/policy that involves multiple funding ministries and participating agencies. A number of instances of the instrumental utilization of findings from an evaluation of multi-site policy and program implementation are discussed. In addition, evaluation practices that served to enhance utilization are presented, including pre-evaluation activities, activities that occurred during the course of the evaluation, and activities performed after delivery of the final report.
