You can direct the method toward a specific problem by choosing provocations related to the problem area.

I've added a paragraph to the Provocation section just now to clarify this:

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).
