This paper tests a theoretically-driven model of self-managing work te
am effectiveness. Self-managing work team effectiveness is defined as
both high performance and employee quality of work life. Drawing on di
fferent theoretical perspectives including work design, self-leadershi
p, sociotechnical, and participative management, four categories of va
riables are theorized to predict self-managing work team effectiveness
: group task design, encouraging supervisor behaviors, group character
istics, and employee involvement context. Data is collected from both
a set of self-managing and traditionally managed teams from a large te
lephone company, and the model is tested with structural equations mod
eling. Support is found for hypotheses concerning group task design, g
roup characteristics, and employee involvement context, but not encour
aging supervisory behaviors.
