   b. false

Solution

Ans: a. true

The use case model reflects the view of the system from the perspective of a user outside of the system (i.e., the system requirements).
The use case model provides an effective means of communication between the business team and the development team. A use case model partitions the way the system works into behaviors, services, and responses (the use cases) that are significant to the users of the system.From the perspective of an actor (or user), a use case should produce something that is of value. Therefore, the analyst must determine what is important to the user, and remember to include it in the use case diagram.
