Final answer:
Activity diagrams can be used to describe processes that involve automated system activities.
Step-by-step explanation:
Yes, activity diagrams can be used to describe processes that involve automated system activities. Activity diagrams are a type of UML (Unified Modeling Language) diagram that visually represents the flow and sequence of activities in a system.
These diagrams show the activities, actions, decision points, and transitions between different states or activities. They can be used to depict both manual and automated activities in a process.
For example, if you have a process where a user submits a form online and the system automatically processes the data, an activity diagram can show the steps involved, including the automated activities.
