When creating Use cases,the mapping between external event and Goal can be N:1
-
True
-
False
In use case modeling, multiple external events (N) can map to a single goal (1). For example, 'click login button' and 'press Enter on login field' are different external events that both trigger the same 'authenticate user' goal. This N:1 mapping is a fundamental concept in use case design.
In use-case/goal modeling, a single business goal can be triggered by several different external events (e.g., "process payment" might be triggered by an online order, a phone order, or a mail-in order) — that's a many-to-one (N:1) mapping from events to a goal. So the statement is True: use-case-to-goal mapping is not required to be strictly 1:1; multiple triggering events can converge on the same underlying goal/use case.
