Use Case
Describe the “Book Hotel” use case based on the Hotwire website at https://www.hotwire.com. Assume
that the customer does not have a Hotwire account and does not want to sign up for a Hotwire account.
Obviously, you are not required to actually make a hotel booking when exploring the website. You will
therefore have to extrapolate what happens after the “Book now” button is pressed. Describe what
happens after the “Book now” button is pressed with a single (and last) step in the main scenario. You
are required to include five alternative/exceptional scenarios in the use case. Use the RUCM tool or one
of the textual templates discussed in class to describe the use case. Even though you are reverse
engineering the use case from an existing website, do not use UI specific terms in your use case. Rather,
abstract from the current implementation and focus on the flow of information and order of steps.
