1. CRITICISM IS NOT ALLOWED

• Judgment of positive and negative ideas must be withheld. No one should criticize anyone else's ideas.

2. FREEWHEELING IS WELCOME

• It is easier to tame down than to think up ideas. Don't be afraid to say anything that comes into your mind-the farther out the idea the better. This complete freedom stimulates more and better ideas.

3. QUANTITY IS WANTED

• The greater the number of ideas, the more likelihood of winners. Come up with as many ideas as you can.

4. PIGGYBACKING IDEAS IS GOOD

• In addition to contributing ideas of your own, suggest how ideas of others can be turned into better ones, or how two ideas can be joined into still a better one.
