# Structure and flow

A piece can have clear sentences and still lose the reader if the ideas
are in the wrong order or do not connect. Structure is the skeleton; flow
is how smoothly the reader moves along it. Both are decided above the
sentence level.

## Method

1. **Choose the organizing principle for the piece's job.** Chronological
   (a story, a process), logical (an argument building to a conclusion),
   priority (most important first, for busy readers; see exec-one-pager),
   or problem-solution. Pick one deliberately; a piece that switches
   principles mid-way disorients.
2. **Outline before or during, and fix structure there.** Get the order
   of sections right when they are cheap to move (an outline), not after
   they are polished prose (see content-outline, editing-and-revision's
   first pass). Each section should have one job and follow naturally
   from the last.
3. **Give each paragraph one idea and a clear topic sentence.** The first
   sentence signals what the paragraph is about; the rest supports it. A
   paragraph covering three ideas should be three paragraphs. Readers skim
   topic sentences, so make them carry the through-line.
4. **Connect with transitions, not just proximity.** Show the reader the
   relationship between ideas: "but", "so", "for example", "in contrast".
   Two true sentences side by side with no connective leaves the reader to
   guess the link. Transitions are the handrail through the argument.
5. **Signpost in longer pieces.** Headings, a brief "here is where we are
   going" up front, and occasional "so far / next" markers let the reader
   keep their place. Structure the reader can see beats structure they
   have to reconstruct (see docs-information-architecture for documents).
6. **Test the flow by reading only the first line of each paragraph.** If
   that skim tells a coherent story, the structure holds. If it jumps or
   repeats, the order or the topic sentences need work.

## Boundaries

- Structure serves the reader and the content, not a template; force-fitting
  a piece into a rigid five-paragraph mold can hurt as much as no
  structure.
- Flow at the sentence level (rhythm, transitions) is a finishing concern;
  get the big-block order right first (see editing-and-revision).
- Different formats have their own structural conventions (a design doc, a
  news article's inverted pyramid, a story's arc); learn the form's shape
  rather than importing one blindly (see press-release, design-doc,
  narrative-craft).
