Abstract
This article states the case for evaluating the effectiveness of problem-solving groups, develops a model of group problem-solving behavior, and applies the resulting conceptual framework to 16 actual evaluations of quality circle programs published between 1981 and 1986. 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.
