It recommends that problem-solving groups be evaluated to improve their effectiveness, that evaluations be comprehensive- attending to feedback variables and to input and process variables, as well as to the commonly measured output variables, and that self-report data-collection pro cedures be supplemented by more objective measures.},  author = {Greenbaum, H.
