Although prior studies increased our understanding of the performance implications of new product development (NPD) team members’ functional backgrounds and demographic variables, they remained relatively silent on the impact of underlying psychological characteristics such as the team members’ cognitive styles on project performance. The goal of this study is to explore the effects of NPD teams’ cognitive styles on project performance in different kinds of NPD projects. Based on survey data from members of 95 NPD teams gathered in four Dutch manufacturing companies, hypotheses about the relationships between teams’ cognitive styles and project performance of radical and incremental NPD projects are tested. Results of linear regression analyses show that the level of teams’ analytical information processing positively affects project performance in both incremental and radical NPD projects, whereas the relationship between the level of teams’ intuitive information processing and project performance depends on the radicalness of the project. These findings contribute to the academic discussion on team innovation, suggesting that, next to demographic and functional characteristics, cognitive styles in teams also significantly influence project performance.
