Customer involvement and NPD cost performance: the moderating role of product innovation novelty

Purpose The purpose of this study is to examine the influence of product innovation novelty on the relationship between customer involvement and new product development (NPD) cost performance. Design/methodology/approach The authors use organizational information processing theory and adopt hierarchical regression and slope difference test to assess the relationships between constructs and test the hypotheses. Findings The authors evaluate the concept of product innovation novelty from the perspectives of suppliers and customers and infer that these two types of product innovation novelty exert a moderate effect on the relationship between customer involvement and NPD cost performance. First, product innovation novelty for customers strengthens the positive effects of customer involvement on the NPD cost performance. Second, product innovation novelty for suppliers weakens the positive impact of customer involvement on the NPD cost performance. The authors also find that the interaction between product innovation novelty for suppliers and product innovation novelty for customers weakens the positive impact of customer involvement on NPD cost performance. Originality/value The findings of this study explain the reasons for the controversies surrounding the impact of customer involvement on cost performance and discuss the role of product innovation novelty in customer involvement in NPD process. The results of this study can be used to establish whether customer involvement improves or weakens NPD cost performance and identify the role of product innovation novelty in NPD. The conclusions derived from this study can provide theoretical knowledge and managerial insights for both academicians and corporate professionals.
