1. Flowcharts
Some Rules

2. Flowcharts as Communication
Since flowcharts are about communication, we must develop some rules
All languages must have rules
Let’s get right in there!

3. Rules for Flowcharts Every flowchart must have a descriptive title
There can be only one start and one end
You should have no more than 2 flowcharts per page
They should be neat!
Decision diamonds are the only shape that can have more than one arrow coming out of it (they can only have two – one yes and one no)
No shape can have more than one arrow coming into it – use flow arrows
The general direction for all flowcharts is from up to down (not left to right)
