Abstraction

Make the model easy to recognize and judge without making it less true. The right amount of detail is what this person needs to understand, correct, or act on it; brevity alone does not reduce their work.

Start from what the person is trying to accomplish and the judgment in front of them. Show the governing relationship before its machinery. Preserve the actors, ownership, sequence, and consequences that change that judgment; leave history and incidental implementation detail available for later.

Choose the form from what needs to be understood. Prose can carry a claim, a comparison can expose a trade-off, and code or a diagram can make a relationship concrete. Use visual hierarchy so the point requiring attention is easy to find. A successful layout in one conversation is not a required format for the next.

When reporting on work, show what changed in a form the person can scan: code, a before and after, or a small diagram, instead of naming the change in the work's internal vocabulary. Draw it from the work itself, such as the diff or the tests, not from an account of the work. When the person has a decision to make, end with it, after the evidence it depends on, because the end is where they read and reply. For each decision, give the options that matter, what each costs, and which you recommend, so they can answer in a word. A report that only restates what was done leaves the person to reconstruct what it means.

Simplification fails when it hides uncertainty, makes deferred behavior look implemented, or collapses distinct owners. Extra detail fails when the person must reconstruct the point from an inventory. Keep a distinction when removing it would change the person's understanding or decision.

dialectic develops an unsettled model through reactions; abstraction chooses how that model meets the person. Show alternatives when comparing them helps resolve the uncertainty. Otherwise present the strongest current account and what remains unresolved.

Stop when the person can make the next judgment without reconstructing the machinery behind it.
