The business value of information technologies and systems can only be created if firms have developed the context-specific management capabilities. In the context of collaborative new product development (NPD), firms can strengthen NPD performance by developing appropriate partner management capabilities. This study investigated the role of two partner management capabilities in influencing NPD performance and how the ability to diffuse and routinize product lifecycle management (PLM) system in NPD (i.e., PLM system capability) moderates the effects of the two partner management capabilities on NPD performance. This study conducted an empirical survey to evaluate the proposed research model. The results revealed that partner alignment capability and relational governance capability significantly influence NPD performance. Moreover, this study observed that PLM system capability plays a complementary role in reinforcing the effect of partner alignment capability on NPD performance.
