Some immediate – but negative – effects of openness on product development performance

This paper charts an unnoticed theme in the current debate on open innovation, namely the foundational question whether increasing openness is beneficial? The paper approaches this question by conceptualising the degree of ‘openness’ and analyses the importance of increasing degrees of openness for NPD performance. Inter-organizational relationships in New Product Development lay the foundation for operationalising openness because these represent important sources of ideas and knowledge in purposive inbound open innovation. This exploratory paper finds that on immediate NPD performance measures the single firm strategy is performing better than the collaborative strategy. However, we also find that the use of internal and external relationships is highly correlated and that these interact with each other. Finally, with increasing degrees of openness the product development projects are slower than the norm in the industry, slower than what is usual for the firm’s projects and had higher cost than the norm in the industry and the firm’s usual projects. These results offer a more critical perspective on openness and NPD performance than the literature on the open innovation paradigm suggests. The paper discusses these results and offers some challenges for management and research of open innovation.
