Flowchart encodes values as topology of labelled boxes and directed edges. Frank Gilbreth process charts, 1921; ANSI/ISO flowchart symbols later.
In reports, ads and assignments it fits decisions, loops and hand-offs in a procedure. Skip it when the structure is a hierarchy or a free brainstorm.
Principles
- Encoding — Flowchart encodes topology of labelled boxes and directed edges.
- History — Frank Gilbreth process charts, 1921; ANSI/ISO flowchart symbols later
- Fit — decisions, loops and hand-offs in a procedure
- Shared baseline — The eye compares length and position more accurately than area.
- Audience — PowerPoint, Excel or Google Sheets and Meta, Google and retail print share the same geometry.
Misconceptions
- Pretty equals true — Decoration rarely persuades; it slows reading.
- 3-D helps — Perspective distortion wrecks comparison. Keep it flat.
- More series is richer — Do not stack stories. One Flowchart, one claim.
- Default palette is fine — Rainbow defaults fail color-blind viewers and grey print. Change Excel or Google Sheets defaults.
Why it matters
- Work — Work: decisions, loops and hand-offs in a procedure. Readable in four minutes in PowerPoint.
- Ads — Ads: one number and one shape speak first in Meta, Google and retail print.
- School — School: for lab reports and poster boards, pick the form that answers the rubric.
- Craft — Craft: honour topology of labelled boxes and directed edges and decoration falls away.
Flowchart: honour topology of labelled boxes and directed edges, and switch when the structure is a hierarchy or a free brainstorm.
