Assumed audience

  • Reading level: comfortable writing documentation; has completed “Audience and Task Analysis.”
  • Background: understands audience analysis and task analysis.
  • Goal: learn to organize documents so readers can find and use the information they need.

Readers don’t read — they scan

Technical documents are not read from beginning to end. Readers scan for the section relevant to their current task, read that section, and leave. Janice Redish argued that web content should be treated as a user interface — readers interact with it the way they interact with software, and the same usability principles apply [@redish2012].

This means the document’s structure is at least as important as its prose. A clearly written paragraph buried under a vague heading is a clearly written paragraph nobody finds.

Headings as navigation

Headings are not decorations. They are the reader’s primary navigation system. A reader scanning a document reads headings first and decides whether to read the text beneath them.

Effective headings:

  • Describe content, not category. “Configuring the database” is more useful than “Configuration.” “How to add a new user” is more useful than “User management.”
  • Use parallel structure. If one heading starts with a gerund (“Configuring…”), others at the same level should too. Parallel structure signals that items at the same level are the same kind of thing.
  • Follow a consistent hierarchy. H2 headings are sections; H3 headings are subsections. Skipping levels (H2 to H4) breaks the document’s logical structure and confuses both human readers and screen readers.
  • Make the document scannable. A reader should be able to read only the headings and understand the document’s structure and scope.

Lists and tables

Lists and tables are not formatting choices — they are structural decisions about how information relates.

Use a list when items are parallel — they’re the same kind of thing (steps, features, requirements). Numbered lists imply sequence; bulleted lists imply no particular order.

Use a table when items have multiple attributes that the reader needs to compare. A table’s power is in its columns — each column is a dimension of comparison. If your “table” has only one column of content, it should be a list.

Don’t use a list or table when the relationship between items is causal, conditional, or argumentative. Prose handles these relationships; lists flatten them.

Progressive disclosure

Progressive disclosure presents information in layers — the essential first, the detailed second, the edge cases third. It manages cognitive load by not presenting everything at once.

In document structure, progressive disclosure means:

  • Lead with the goal. Start each section by telling the reader what it covers and why it matters.
  • Put the common case first. Document the typical workflow before the exceptions.
  • Nest complexity. Details, caveats, and edge cases go in subsections, footnotes, or expandable content — not in the main flow.
  • Link to depth. If a topic has its own page, link to it rather than reproducing it. The reader who needs depth will follow the link; the reader who doesn’t will keep moving.

John Carroll’s minimalist documentation research found that readers learn faster from stripped-down materials than from comprehensive manuals [@carroll1990]. The implication is counterintuitive: less documentation, better organized, outperforms more documentation poorly organized.

Genre as architecture

Carolyn Miller defined genres as “typified rhetorical actions” — recurring situations that produce recurring forms [@miller1984]. In technical writing, this means that content types (term definitions, tutorials, reference pages, how-tos) carry structural expectations. A reader who opens a how-to expects numbered steps; a reader who opens a reference page expects a systematic listing of options.

These expectations are architectural. When a document follows its genre’s conventions, the reader can navigate it using prior experience with similar documents. When it departs from convention — a how-to organized as an essay, a reference page written as a narrative — the reader loses that navigational advantage.

The content types in this vault are genres in Miller’s sense:

  • Term definitions: opening definition sentence, elaboration paragraphs, related terms.
  • Lessons: assumed audience, substantive sections building toward understanding, guidance section.
  • Index pages: brief description, entries list with enough context to orient.

Following these patterns consistently is not rigidity — it’s architecture. Each page is easier to write and easier to navigate because it follows a known form.

Guidance

  • After drafting, read only the headings. If they don’t tell the document’s story on their own, revise them.
  • Use the “five-second test”: show the document to someone for five seconds. Can they tell you what it’s about and where to find the main content? If not, the structure needs work.
  • When a section grows beyond a screen of text, consider whether it should be split into subsections or broken into a separate page.
  • Before adding a section, ask: does the reader need this to complete their task? If not, move it to an appendix, a linked page, or nowhere.
