Shared leadership in project teams: An integrative multi-level conceptual model and research agenda (4/35)

Shared leadership has rarely been studied in the project management context, despite its proven performance-enhancing benefits in other management domains. Based on a systematic review of the salient literature from multiple disciplines, this paper develops a new multi-level conceptual model to advance a holistic understanding of how shared leadership develops and how it may impact individual, team, project and wider organizational performance. The conceptual model draws upon the input-mediator-output-input perspective of systems theory, which is well-established in the general team literature. The new integrative model identifies the potential multi-level antecedents, proximal team functioning outcomes, and the more distal multi-level outcomes of shared leadership based on findings from the shared leadership literature drawn largely from other domains. Potential boundary conditions of the model are identified. A future research agenda is recommended for empirically testing the new multi-level shared leadership model and its different elements in a diverse range of project contexts.
