Single‐site, results‐level evaluation of quality awareness training

A Crosby quality‐training intervention was studied in a single facility to evaluate its long‐term effects in terms of both quality level and dollar utility. Using an interrupted time‐series design pooling six twelve‐year series, this study found that the training demonstrates a positive effect size for the quality level of the goods produced in a vitreous china plant and has a positive dollar utility. The study also revealed an important contextual factor—production process—in the evaluation of the effect size of a quality‐training intervention. In addition, the analysis method—a fixed effects model—was shown to be useful for studying training interventions in single facilities where there are multiple product lines.
