Problem statement: Move this object from point A to point B.

The action verb is "move." Some synonyms are push, pull, slip, slide, shove, throw, eject. jump, spill.

By whatever means, the aim in this ideation step is to generate a large number of ideas without particular regard to quality. But, at some point, your "mental well" will go dry. You will have then reached the step in the creative process called frustration. It is time to leave the problem and do something else for a time. While your conscious mind is occupied with other concerns, your subconscious mind will still be hard at work on the problem. This is the step called incubation. Suddenly, at a quite unexpected time and place, an idea will pop into your consciousness, and it will seem to be the obvious and "right" solution to the problem ... Eureka! Most likely, later analysis will discov- er some flaw in this solution. If so, back up and iterate! More ideation, perhaps more research, and possibly even a redefinition of the problem may be necessary.

In "Unlocking Human Creativity"[S] Wallen describes three requirements for cre- ative insight:

• Fascination with a problem.

• Saturation with the facts, technical ideas, data, and the background of the problem.

• A period of reorganization.

The first of these provides the motivation to solve the problem. The second is the back- ground research step described above. The period of reorganization refers to the frustra- tion phase when your subconscious works on the problem. Wallen[S] reports that testi- mony from creative people tells us that in this period of reorganization they have no con- scious concern with the particular problem and that the moment of insight frequently ap- pears in the midst of relaxation or sleep. So to enhance your creativity, saturate yourself in the problem and related background material. Then relax and let your subconscious do the hard work!

Analysis

Once you are at this stage, you have structured the problem, at least temporarily, and can now apply more sophisticated analysis techniques to examine the performance of the

design in the analysis phase of the design process. (Some of these analysis methods will be discussed in detail in the following chapters.) Further iteration will be required as problems are discovered from the analysis. Repetition of as many earlier steps in the design process as necessary must be done to ensure the success of the design.
