Information Hierarchy

The reader should get the answer in the first thing they see, and find depth only when they reach for it. Everything else here follows from that: each beat of the piece takes the form that carries it best, what matters most comes first, and the medium stays as simple as the content allows.

Lead with the answer/conclusion

Readers scan. Open with the finding itself, and the piece works in thirty seconds. The same logic repeats at every scale: a section's first sentence is its answer, a slide's title is its takeaway ("Cache misses double p99" rather than "Performance"), a UI label carries its whole meaning alone.

Behind the answer sits depth (reasoning, evidence, edge cases), and behind that, sources. Keep depth that most readers will skip, and move it: a later section, a linked page, a footnote. Sources belong at the end.

Pick the form that fits the idea

Prose is the default; break from it when another form genuinely carries the idea better. An example grounds an abstract claim faster than more explanation. A table holds enumerable facts that prose would bury. A chart shows a trend that a sentence can only assert. A mockup shows a layout the reader would otherwise have to imagine.

Diagram-first for pipelines and relationships. When the content is a pipeline, a dependency graph, a state machine, or any structure where the relationship between parts is the hard idea, put the diagram early — a one-sentence takeaway, then the diagram, then detailed prose. The diagram leads, the prose still explains; prose alone buries the shape. Keep inline diagrams to a handful of nodes and give larger structures an explorable view. Validate diagrams (see /creative-writing-skills:md-validation).

Ask what the beat is trying to do, then give it the form that does that: an explanation gets a paragraph, a comparison gets a table. Each form teaches best inside its own job: a diagram standing in for an explanation teaches less than the paragraph would.

Match hierarchy to the medium

For any medium, ask one question: can it hide content until the reader asks for it? Chat, email, and plain documents show everything at once, so hierarchy there means density and order: every early sentence pays for itself, and depth lives behind a link. Media that can hide (HTML, apps, anything with expand or navigate) may fold depth into collapsed sections, popovers, or child pages. Reserve each interaction for depth a reader will actually reach for.

Structure helps the scanner in every medium: headers that carry the argument on their own, asides for context off the main thread, a table of contents when the piece is long enough to need a map. These organize the surface; putting the answer first remains the job of the writing itself.

Choose the simplest medium that presents every beat well: a tight reply beats an HTML site whenever both would teach the same thing. When HTML is earned, build it phone-first and use /creative-writing-skills:structured-artifact.
