Bits and Pieces, February, 1990, p. 20
Years ago a professor at Stanford devised a check lest of nine questions that can be applied to any problem. Used as a self-quiz, the questions spur imagination. They are:
1. Is there a new way to do it?
2. Can you borrow or adapt?
3. Can you give it a new twist?
4. Do you merely need more of the same?
5. Less of the same?
6. Is there a substitute?
7. Can the parts be rearranged?
8. What if we do just the opposite?
9. Can ideas be combined?
