Actions and Flows

Understanding Action

An Action in Modeldraw's Activity Diagram tool is represented by a rounded rectangle with the action's name inside. Key points to understand about Actions include:

• Actions are the most fundamental elements of behavior in Activity Diagrams.

• Each Action should have a clear, descriptive name indicating what it does.

• An Action is considered to be atomic, meaning it's executed as a single, uninterrupted unit of work.

• Actions can have one or more incoming flows and one or more outgoing flows.

• Unlike composite activities or sub-processes, an Action doesn't have any internal flow or structure visible in the diagram.

• Actions are typically named using a verb-noun format to clearly describe the operation being performed.

Remember to use clear, concise names for your Actions that accurately describe the step or task being performed.
