Too Long; Didn't Read
An open innovation challenge is an initiative promoted by organizations, a community or a public institution. Henry Chesbrough, a professor at the University of California Haas School of Business, coined the term “open innovation” almost 2 decades ago. People should be encouraged to take risks, thus the nature of a challenge is to generate ideas, POCs (proof of concepts) or Prototypes and not production-ready products. The next step is to prepare the right set materials to describe your proposal and publish your challenge to a broader community.
