The purpose of this paper is to discuss the reasons for resistance to evaluation and the factors that affect adoption of new procedures, while focusing on a model for guiding the planning of evaluation implementation strategies. The process of adoption of an innovation occurs in three stages: orientation, where the user identifies benefits; initiation, where the user gives an innovation a trial; and integration, where it becomes part of routine practice. At each stage in the adoption, different strategies can be directed to gain the cooperation of either the user of the evaluation or the organization: (1) power; (2) communication; (3) consultation; (4) reinforcement; (5) training ; and (6) direct measures. The strategies differ depending upon the time frame in which they are applied. That is, different operations are required prior to commencement, during the initiation of the evaluation, and when evaluation procedures are to be integrated into routine organizational activities. It is concluded that: (1) in planning the implementation of evaluation, the implications are that implementation strategies should persuade rather than enforce cooperation; (2) cognitive and perceptual changes must be accompanied by behavioral changes; and (3) different management practices will be applicable at different time intervals in the evaluation procedure.
