邀请其他人参与你的早期设计思考，简单直接地拉到白板前讨论好过给出详细的文档。

Try to keep the clay wet. Rather than writing up a document or creating a slideshow, invite them to a whiteboard and redraw the elements as you worked them out earlier, building up the concept from the beginning.

Stick completely to the concept you already worked out to get feedback on the work you’ve already done. Then once you’ve covered the work you already did, open it up and invite them to suggest revisions. Having seen this concept, do they have any insights about how to drastically simplify or approach the problem differently?
