Executives and managers talk constantly with suppliers, consultants, regulators, and other stakeholders. Why, then, hasnât open innovation made a bigger difference? Why isnât the typical corporation as resilient and innovative as a city or a university? Because, to put it bluntly, theyâre often run by people whose minds are hermetically sealed against unconventional ideas.
