First of all, define all your actors to your system (Client,
Administrator, Arming Loop, etc.).
Then define all the responsibilities for each actor, those
responsiblities are your Use Cases.
* Enter Parking with Credit Card (Client Actor)
* Enter Parking with Ticket (Client Actor)
* Configures System for One Barrier (Administrator Actor)
* Configures System for Two Barriers (Administrator Actor)
* Recognizes Car Passage through the Barrier (Arming Loop)
* etc.
Now you have your system boundries defined. Then finish each Use Case
with the details (Description, Pre & Post Conditions, Flows, Special
Requirements).
What I gave above is an example, I don't know much about the system
being written but I think this might give you a good start.

Subject: (ROSE) Use Case versus generic system
Hi all,
We start a system for the parking area. The purpose of it his to
manage the
entry/exit of the client. The system could be connect to an
barrier, an
arming loop (a device that capture the passage of the car), en
entry device
(that have button for the ticket, credit card reader etc). My
question is
about the approach to define a use case like 'Client enter in
the parking'
for a system that could have different configuration. We want to
let our
customer be able to configure the entry like they want. That
means they
could decide to include a credit card reader or not, to have two
barrier or
one etc. I ask myself what approach to take to define my use
case ? What
could be me primary scenario ? Even with a configuration, the
client that
enter in the parking could take many path, like to use the
credit card
reader instead of the button to take a ticket.
An help will be very appreciate
Thank you
Yves Gagnon
