Process Element - Modeling Actions in Flowchart

What is the Process Element?

The Process element in a flowchart is represented by a rectangular shape and is used to denote an action or operation that needs to be performed. This could be anything from a single step in a task to a complete process within a larger system. The Process symbol is foundational in flowchart design due to its ability to clearly define actions.

Characteristics of the Process Element

• Shape: The Process symbol is typically depicted as a rectangle.
• Purpose: It models actions or operations within a procedure, algorithm or complex process.
• Connections: It can be connected to other Process elements or different flowchart elements such as decisions, inputs/outputs, and start/end symbols.

How to Use the Process Element in Flowcharts (Step-by-Step Guide)

• Identify the Actions: Before you start drawing your flowchart, think about all the actions or operations that need to be represented.
• Draw the Process Elements: For each action, draw a rectangular Process element on your flowchart.
• Label Each Process Element: Clearly label each rectangle with the action or operation it represents.
• Keep it Simple: Ensure that each action shape is labeled clearly and concisely. Avoid overly complex descriptions that could confuse readers. For example, "Receive Order," "Process Payment," or "Ship Product."
• Connect the Elements: Use Flow connectors (arrowed lines) to link the Process elements. These connectors indicate the flow of operations from one action to the next.

Flowchart Process Element and UML Action

The Process element in flowcharts is equivalent to the Action element in UML (Unified Modeling Language) Activity Diagrams. Both are used to represent an action or operation within a system. However, the terminology and shapes differ slightly, with UML using a more complex set of symbols and notations.
