Initial Node

An Initial Node in an Activity Diagram represents the starting point of the activity or process being modeled. It indicates where the flow of control begins in the diagram.

With Initial Nodes in Modeldraw's Activity Diagram, you can:

• Clearly mark the beginning of your activity or process

• Provide a single, unambiguous starting point for the diagram

• Initiate the flow of actions in your activity

• Ensure that your diagram has a well-defined entry point

• Start modeling complex workflows or algorithms from a clear beginning

Understanding Initial Node

An Initial Node in Modeldraw's Activity Diagram tool is represented by a solid black circle. Key points to understand about Initial Nodes include:

• It marks the beginning of the activity flow.

• There should be only one Initial Node in an Activity Diagram.

• An Initial Node cannot have any incoming flows.

• It typically has one outgoing flow leading to the first action or decision in the activity.

• Initial Nodes don't perform any actions themselves; they simply indicate where the process starts.

• The flow from the Initial Node to the first element is considered to be automatic and immediate.

Remember that you should have only one Initial Node in your Activity Diagram, and it should be connected to the first step of your process.
