Mr. Malfoy is new to the business of having ideas, and so when he has one, he becomes proud of himself for having it. He has not yet had enough ideas to unflinchingly discard those that are beautiful in some aspects and impractical in others; he has not yet acquired confidence in his own ability to think of better ideas as he requires them. What we are seeing here is not Mr. Malfoy's best idea, I fear, but rather his only idea.

I want to emphasize yet again that the tools [described in Serious Creativity] are deliberate and can be used systematically. It is not a matter of inspiration or feeling in the mood of being "high." You can use the tools just as deliberately as you can add up a column of numbers.

- Edward De Bono, Serious Creativity

I will summarize some of the techniques for how to generate ideas presented in Serious Creativity. The book also has other material, e.g. interesting deep theories about why these techniques work, arguments for the importance of creativity, and more techniques beyond what's described in this post, but in the interest of keeping this post concise and useful, I will only describe one kind of technique and urge you to just try it. You should read the book if you want more detail or techniques.

These techniques can be used both when you have a problem you need to solve and when you have a general area that you suspect could be improved or innovated, but don't have any specific ideas of what's wrong (or even if you don't feel like there's anything wrong at all).

The technique I will describe in this post is that of "provocation" followed by "movement." A provocation is a seemingly random or nonsensical sentence or phrase. Movement is the process of going forward with a provocation and actually generating an idea. There are precise, formal techniques for generating provocations and movement, which I will describe after giving an example of how this "provocation-movement" process works.

Example

Provocation: Planes land upside down.
Movement: We can imagine this actually happening, and observe that the pilot would have a better view of the landing area. This naturally leads us to consider other ways to improve the pilot's view of the landing area. Perhaps we could move the cockpit to the bottom, or add video cameras. So using this technique, we've identified an area for improvement and two possible ways to make that improvement.

Setting Up Provocations

Provocation is a way to avoid getting stuck in the same "mental pathways" (see priming) so that you can find new ones. Provocations should not make sense and are not necessarily intended to convey meaning; they are just intended to "make things happen in our minds." The book precedes provocations with "po," a word used to indicate that the sentence is intended to be nonsensical and illogical. Po stands for "provoking operation." The book describes several techniques for generating provocations.

1. Escape method: Think of something that we take for granted, and negate it. E.g., "Po, restaurants do not have food" or "Po, shoes do not have soles."
2. Reversal: Take a standard arrangement or relationship that we take for granted, and reverse it. E.g. "I have orange juice for breakfast" becomes "Po, the orange juice has me for breakfast". Note that the reversal would not be "Po, I do not have orange juice for breakfast." That would be the escape method.
3. Exaggeration: Suggest that some dimension or measurement falls far outside its normal range (either greater or lesser). E.g. "Po, every household has 100 phones" or "Po, the phone has 1 dialing button." If you're making the dimension smaller, do not bring it to 0 or you're just using the escape method again. E.g. "Po, the phone has 0 dialing buttons" is not an exaggeration, it's an escape.
4. Distortion: Take normal arrangements (e.g. relationships or time sequences) and switch them around. E.g. "Po, you close the letter after you post it," "Po, criminals pay for the police force," or "Po, food prepares customers for chefs."
5. Wishful thinking: "Wouldn't it be nice if..." put forward a fantasy that is known to be impossible. E.g. "Po, the pencil should write by itself."

A provocation doesn't need to follow from one of these techniques. A provocation can be any incorrect or absurd statement. These techniques are just easy step-by-step ways to generate provocations without requiring any elusive "spark of inspiration." Once a provocation is generated, it should be followed by one or more of the movement techniques described in the next section.

If you are trying to solve a specific problem or innovate in a particular domain, then choose provocations related to the domain. That is, if you're trying to figure out how to improve wikipedia, don't use a provocation like "Po, the orange juice has me for breakfast," choose one like "Po, citations are not needed" (escape) or "Po, articles contain encyclopedias." (reversal).

Movement

Movement allows you to take some idea, concept, or provocation and move forward with it to generate more useful ideas and concepts. These techniques don't apply solely to provocations: you can use them for ideas and concepts too. The book describes 5 formal techniques for movement:

1. Extract a principle: Focus on some principle of the provocation, and then work with that principle to discover other ideas related to it. E.g. with the provocation "Po, bring back the town crier", we may extract the principle that the town crier can go to where people are, and then we try to generate ideas related to that principle.
2. Focus on the difference: Compare the provocation to existing ways of doing things. How are they different? Then you can consider other ways to use this difference. This is very similar to "extract a principle."
3. Moment to moment: imagine what would happen if the provocation were put into effect. We are not interested in the final effect, but the moment-to-moment happenings. E.g. for "Po, orange juice has me for breakfast", you may imagine yourself falling into a giant glass of orange juice.
4. Positive aspects: Look directly for benefits. What are the positive aspects of the provocation? Once you've identified some positive aspects you can consider if you can achieve some of them in other ways (again, this is similar to extract a principle, it's just another way of thinking about it).
5. Circumstances: In what circumstances would the provocation have immediate value? E.g. for the provocation "Po, drinking glasses should have rounded bottoms," you could notice that this would be useful if you didn't want people to be able to put down their glasses. This could be good for bars, where you want people to drink more and faster.

You can use these movement techniques not just on provocations, but also ideas or concepts. For example, you may start with a provocation, use the "moment to moment" technique which gives you an idea, and then you could use the "positive aspects" technique with that idea to generate more ideas. Also, of course, you do not need to strictly use just these techniques. If a provocation directly leads you to think of something interesting without explicitly choosing to use one of these techniques, that's fine, you should explore the idea more. Use these when you need them.

More Examples

Here's another example from the book. This one uses the "moment to moment" movement technique:

Po, cars have square wheels

We imagine a car with square wheels. We imagine this car starting to roll. The square wheel rises up on its corner. This would lead to a very bumpy ride. But the suspension could anticipate this rise and could adjust by getting shorter. This leads to the concept of an adjusting suspension. This in turn leads to the idea of a vehicle for going over rough ground. A jockey wheel would signal back the state of the ground to the suspension which would then adjust so that the wheel was raised to follow the "profile" of the ground...This was an idea I first suggested about twenty years ago. Today several companies such as Lotus (part of GM) are working on "intelligent suspension" which behaves in a similar way.

And here's another one from the book. The provocation uses the "escape" method and the movement seems to use the "circumstances" method:

Po, waiters are not polite.

This leads to an idea for waiters to be actors and actresses. The menu indicates the "character" of the waiter. You can order whichever waiter you wanted: belligerent, humorous, obsequious, and so on. You might order a belligerent waiter and enjoy having a fight with him. The waiters and waitresses would act out the assigned role.

Warnings

• As a general principle, try to avoid saying "oh, but this is just like this other existing product" whenever you generate an idea. Usually it's not just like the existing idea, you're just interpreting it in that way because we naturally follow paths toward the familiar. So if you have a half-formed idea that could take several directions, fight the urge to immediately take it down an existing path and then discard it because it already exists. Leave it in the half-formed stage instead. I'm reminded of the concept of semantic stopsigns. Saying an idea is "the same as" something else gives the illusion of having fully explored the idea, when in reality you just jumped immediately to one possible development (possibly the least useful development, since it's one you know already exists).
• Similarly, do not take too many steps when moving from a provocation. This will just lead you to an existing idea. There's nothing to be gained by playing 6 degrees of separation with provocations and existing ideas. Just take a few small steps. If nothing comes to you, try other movement techniques or try a different provocation. 
• You're not expected to come up with a good idea for every provocation. Most of the time you'll come up with some mediocre or half-formed idea, or even no idea at all. This is fine.
• You should write down anything you come up with that seems interesting (even if it's a bad idea in its current form, if it has something interesting about it, write it down) and then come back to it later and think about it more (either using these techniques or just your normal thinking processes for improving and adapting ideas).
