Three evaluators with different backgrounds and interests were involved in a program evaluation at Cornell University's Center for International Studies, where two of the evaluators had serious conflicts and the third served as an in-house mediator. The third evaluator questioned why he had credibility with the first two, looked at how he developed professional and interpersonal skills, examined how he reinforced a task-oriented atmosphere, analyzed how he worked, assessed his role effectiveness, and summarized how the entire process helped him. He saw his role as that of a facilitator/consultant/problem solver. (BJG)
