Several decades of research into innovation management have failed to provide clear and consistent findings or coherent advice to managers. In this paper, I argue that this is because innovation management ‘best practice‘ is contingent on a range of factors, and that we need better characterizations of the technological and market contingencies which affect the opportunity for, and constraints on, innovation. I review research on innovation together with relevant studies from organizational behaviour and strategic management, and develop a model which may help to guide future innovation research on the relationships between environmental contingencies, organization configurations and performance. I identify uncertainty and complexity as the key environmental contingencies that influence organizational structure and management processes for innovation.
