What does an activity partition convey?

What does an activity partition convey?

• A. The structure that performs each action
• B. The data produced by actions
• C. The overall duration of the activity
• D. The lifelines participating

Answer: (A)

Activity partitions (swimlanes) show who is responsible for each action in a workflow. By grouping steps into lanes assigned to a person, role, or unit, they reveal the structure of responsibilities and how work moves from one performer to another. This makes it clear which part of the organization executes each step and how handoffs occur. They don’t directly depict data produced, overall duration, or lifelines; those aspects are represented by data objects, timing information, or sequence diagram elements. So, the partition conveys the structure that performs each action.
