Proven To Increase Number Better Ideas:
Phase One: Be open to new ideas, without judgement or self-consciousness. This frees the brain. Otherwise the bran is more focused on preserving the status quo. Feel safe to share. Ask not to be held accountable for brainstorming and what's said. Applies to how Innovation Institute often communicates options and theories.
Phase Two: Pick the best of the ideas. Play around with them.
Phase Thee: Take the best idea and perfect it. Think both inside (grounded) and outside the box (innovative).
