Traditionally the protection of intellectual property is regarded as a precondition for value capture. The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product’s source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.
