Open Ideas are ideas that team members create outside of the parameters of a challenge whereas Challenge Ideas are ideas that have been created based on the parameters of a Challenge.
Ideas generated from Challenges are done so with the help of an overview, description of what success looks like, and what the strategic focuses are. This gives a lot more direction as to what ideas should look like than Open Ideas.
Challenge Ideas are also much higher level. The goal of a Challenge is to collect as many high level, strategically aligned ideas as possible in a set period of time. That is why Challenge Ideas are brief, with a 50-word maximum for the description.
