The Effects of Quality Circles on Performance and Promotions
通过准实验设计比较118名质量圈成员与118名非成员，发现参与质量圈一年后成员获得更高绩效评分和更多晋升机会，并讨论了可能原因。
This study was designed to test the developmental effects of quality circles (QCs) on participants' job performance and promotions. A quasiexperimental design was used to compare 118 circle members with 118 noncircle employees. In the year following the circle intervention, circle members received significantly greater performance ratings and were promoted morefrequently than non-members. The developmentalproperties of the QC process believed responsible for these findings are discussed. Other possible explanations for the results are also proposed: visibility, positive evaluation bias, and anticipatory socialization.
