Effects of designers' participation and their evaluation measures on simultaneous achievement of quality and cost of product development teams

摘要

This paper reports the results of an empirical study designed to investigate the effects of alternative participation of the designers and their performance-evaluation measures on Simultaneous achievement of quality and cost in product development. These effects are tested in the weight-determination process at different deployment teams of QFD for model change product. The findings are based on a questionnaire survey of 207 Japanese manufacturing companies. We tested the interaction effects of three levels of participation and two levels of evaluation measure on quality and cost performance by the proportional-odds model. Results show that in all deployment teams, joint-participation (JP) is the dominant category. At mechanism deployment, simultaneous attainment of quality and cost is possible by JP and evaluation by uncontrollable information (UC). At the function and parts deployment teams, JP is the most effective when it is interacted with controllable information (C). The difference in the results in mechanism, function and parts levels lies in the controllability of the evaluation measures, which corresponds to their team sizes. The UC is associated with the teams having complex and broader structure while C is with simple and small structured teams.
