Use Case Diagram Exercise | Intermediate Exercises – Identifying elements
Try to draw use case diagrams for the following. You will need to identify the actor, system, and use

Use Case Diagram Exercise | Advanced Exercise – Multiple elements
Note: It may be helpful to first identify the system, the actor, and use cases before starting to
create the use case diagram. While you may find additional elements, only the those that are
explicitly mentioned need to be included.
Next you are given a series of more advanced exercise. Create a use case diagram for the following:
5. On your first day as a systems analyst, you have been asked to create a use case diagram
outlining the requirements of a completely automated university library system. You have been
given the following information.
Students can borrow books from the university library. Occasionally, the books are returned
late and a fee is issued the student needs to pay. Sometimes a student is unsure of where the
book is located and will use the university library system to look up the location of the book.
If unsure of

Use Case Diagram Exercise | <>
Notes:
Have a go at the following exercises. Recall that an <> association indicates that all instances
of the base use case will always result in at least one instance of the included use case. Without the
included use case, the base use case would be incomplete. Take care when indicating the direction of
the association!
6. System: ATM System
Actor: Customer
Base Use Case: Withdraw Cash

Use Case Diagram Exercise | <>
Have a go at the following exercises. Recall that an <> association denotes a condition that
needs to be met before the extended use case takes place. That is, the extended use case is an optional
action that may be undertaken once the preceding use case has occurred. Take care when indicating
the direction of the association!

Use Case Diagram Exercise | Expert
The following exercise requires you to put everything you have just practised together. Read the
narrative carefully. While you might identify additional correct associations/use cases not explicitly
mentioned, you do not need to document those (although its good practise)! Read carefully and try to
separate important information.

13. A customer wants to rent a movie and/or a video game at a physical rental store. When
renting either product, they must be registered customers of that store. Registration is free
and done on the system with the assistance of a staff member. Both customers and staff
members want to be able to find movies/games either though the system. Customers can
only make payments for rentals and late fees though a credit card. At this store, customers
have the option to rent a video game console in addition to a video game or movie.
Customers may not rent a console without first renting a movie or game. At some point during
the rental period, customers will return the movies, games, and/or consoles to the store which
needs to be processed through the system by the clerk.
