Why use it?
Flowcharts are the most misused notation in the world — the full symbol set says exactly what each step is.
When it helps
Documenting procedures for a general audience.
How to read it
- Read top to bottom following the arrows; every symbol has one meaning.
- Decisions have exactly the branches their labels claim.
What you need
- The steps and their types
- The branches
- Start and end points
Things to check
- Do not use a process box for a decision (or vice versa).
- Do not leave a branch unlabeled.
Scope of this diagram
Notation coverage of the ISO 5807 symbol set; no simulation of the procedure.
