Leading innovation in an inter-organizational team together: the moderating role of shared leadership behavior in the transitioning between different phases of the open innovation process

Purpose This study aims to contribute to the open innovation (OI) literature by investigating the transitions between three phases in the OI process (i.e. idea generation, idea promotion and idea realization) and how these are moderated by different forms of shared leadership (i.e. transactional, and transformational) as perceived by participants in the OI process. Design/methodology/approach The authors tested a set of hypotheses using moderated mediation PLS-SEM models on a bootstrapped sample of OI participants (N = 173). Findings The authors found a direct relationship between idea generation and realization, as well as indirectly through idea promotion. This study implies that the promotion of ideas by participants can be beneficial in inter-organizational OI teams, as promotion of ideas provides a linkage between the generation of ideas and the idea realization phase. However, while shared leadership has been shown to be beneficial in conventional teams, the authors found evidence that this may not be the case in inter-organizational OI teams. Higher levels of shared transformational leadership from colleagues with whom employees do not share the same organizational background may hamper the promotion of ideas. Originality/value In contrast to the mainstream view, the authors found significant evidence that transformational shared leadership negatively moderates the direct relationship between idea generation and the promotion of ideas and the indirect relationship between idea generation and realization via idea promotion.
