In principle, good group decisions are creations. Creativity comes from putting together two or more things, events or ideas. Germination leads to new creations. Like water with a poppy seed, fertile soil facilitates and supports the interaction. Fertility helps creativity.
Practical Tip: Make your decision-making environment “fertile.” Through the design of meetings and communications, facilitate the interaction of multiple ideas. Make a culture of support and nurturing for new ideas. This might be done through ground rules or operating norms. Be consistent in their application. Uphold and stand by your ground rules in all situations. Deliberately attend to and nurture the environment in which you are trying to grow.
