In order to succeed in today’s business environment, organizations face the challenge of not only coming up with creative ideas, but also developing the most promising ones faster and more effectively than the competition. This typically involves different people working at different stages of the creativity and innovation process and also requires their collect ive support. As a result, most people typically end - up working on creative ideas that others have had – with the initial idea generators not even involved in their subsequent development. Curiously, however, researchers and practitioners alike lack sound t heoretical bases to examine the extent to which people’s ‘relationships’ or ‘attachments’ with creative ideas might impact the flow of these ideas through organizational creativity and innovation processes. In order to address this situation, we integrate theories of psychological ownership and social identity to develop a model of the social - psychological dynamics regarding how different organizational actors relate to different ideas. By drawing attention not only to the parallel effects of ownership and identification dynamics, but also to their interplay at both the individual and collective level, we contribute novel insights about how these dynamics might reinforce one another to support the successful development of creative ideas across the innovatio n process.
