Combining internal quality-oriented product design with external supplier involvement for enhancing operational performance: the moderating role of product modularity

Abstract

Purpose

The purpose of this study is to develop a moderated mediation model by which quality-oriented product design practices influence operational performance via supplier involvement under the different levels of product modularity.

Design/methodology/approach

The authors use the multisource data from 268 manufacturing firms worldwide and apply regression and the PROCESS macro model to test the moderated mediation model.

Findings

The findings reveal that quality-oriented product design practices enhance operational performance directly and do so indirectly through promoting supplier involvement in quality improvement. In addition, this indirect effect is stronger when the level of product modularity is high.

Originality/value

By exploring the interaction effects of quality-oriented product design and product modularity, this study provides valuable insights into the ways in which manufacturing firms improve operational performance more effectively.
