Build a nonfiction outline around reader questions
An outline becomes useful when it follows the questions readers need answered, including the questions created by earlier answers.
Writing
An example should make a distinction, process or consequence easier to understand. Choose it for that work.

Suppose a chapter explains the difference between a recurring cost and a one-off cost. A long anecdote about starting a business might contain that distinction, but readers may have to work to find it. A short comparison between buying a printer and replacing its ink can make the point directly. The example's scale should match the idea it serves.
Write the claim in a sentence, then ask what a reader is likely to misunderstand. They might confuse two categories, miss a sequence or assume that a rule has no exceptions. Select an example that addresses that particular difficulty. Interesting material that does not repair a likely misunderstanding may be better saved for another passage.
The strongest example is not always the most unusual. A familiar situation can reduce the amount of background explanation needed. An unfamiliar case can be valuable when it reveals a limit that ordinary cases conceal, but introduce its relevant features before asking the reader to draw a conclusion.
When comparing two examples, keep irrelevant differences to a minimum. If you change the person, setting, budget, aim and timescale at once, readers may not know which difference explains the outcome. You can use a deliberately simplified hypothetical pair to isolate a principle, provided the simplification is clear and does not misrepresent the subject.
For instance, an illustrative comparison of two workshop schedules could keep the task and available hours constant while changing when the work is divided. The point is then visible. You should not present invented figures as results from an actual organisation. Label a made-up situation as hypothetical or illustrative where a reader could otherwise mistake it for evidence.
After the example, explain the connection briefly. Do not assume that the reader has extracted precisely the lesson you intended, but avoid retelling the entire example in abstract language. One sentence identifying the important difference may be enough.
A single successful case can make an approach appear more universal than it is. Add a contrasting case if the distinction matters. An example may show when a method works; a counterexample can show which condition makes it fail. The pair helps readers recognise the scope of the advice.
Be careful with real people's experiences. Check the source, preserve the context and avoid turning a complex account into a convenient moral. If an example depends on a fact you cannot verify, choose a different example or state the uncertainty. The vividness of an anecdote does not increase its reliability.
During revision, list the job of every substantial example in a chapter. If several have the same job, retain the clearest or make the differences meaningful. If a difficult claim has no example at all, consider adding one there. This distributes concrete material according to reader need instead of scattering anecdotes simply to make the pages feel lively.
