How to use Flow Diagram

Whats the history and context of the “Flow Diagram” feature where you create squares and rectangles to represent stages of the work flow. Is the purpose of this feature so teams can double check that they have created software that accurately depicts the user journey? Other explanation how its used?

It’s just a flowchart creation tool. I don’t know if it’s different in RP10 from the way it’s been up through RP9, but the built-in “flow” widget library has lots of flowchart shapes, and switching from “select” mode to “connect” mode will let you draw arrows between connection points on the shapes. Moving the shapes around will cause the arrows to re-render so they stay connected to their shapes.
