Fifteen years ago, Henry Chesbrough developed the term „Open Innovation” to describe the process of managing knowledge flows across widely distributed sources for the purpose of generating new products, services or business models. Today, innovation-driven organizations do no longer decide whether to initiate open or closed innovation processes, but rather how to design effective ways of managing openness and collaboration in their innovation activities. Innovation is a paradigm that assumes that companies can and should use ideas from inside the company as well as from outside and rely on internal and external pathways to the market when advancing their technologies. Open Innovation combines internal and external ideas to architectures and systems whose requirements are defined by a business model.
