Which of the following is an activity in Appian process models?

• A. Gateways
• B. User Tasks
• C. Subprocesses
• D. Sequence Flows

Answer: (B)

In Appian process models, an activity is a step where work is performed. A User Task represents the human work item to be completed, usually by a specific user or group, and often includes a form for input and metadata like assignee and due date. Gateways are the decision points that determine which path to take in the flow, not work being done. Subprocesses are containers for running another process model, serving as a reusable unit rather than a single activity. Sequence Flows are the connectors that define the order between nodes, not activities themselves. So the option that best fits an activity is the User Task.
