The Visible rules are built into Visible Analyst to give you guidance and to provide
consistency in carrying out your activities. The various methodologies supported by your tool
set(s) are codified in the rules. They are implemented in two different ways. Some are
applied as you draw items onto project diagrams. Violations of the methodologies are not
allowed and certain required actions are automatically taken. Other rules are applied on
request when you execute the Analyze function from the Diagram menu. Analysis also
displays some error and warning messages, suggesting further action for you to take.
