Hi
I think that you should assume one path as being your 'happy day' scenario
and then consider all other cases as 'alternative scenarios'. this will
hopefully become more apparent when you proceed to produce the sequence
diagram for the use case 'enter car park'.
I would suggest that your primary scenario should be:
driver inserts card -> reader validates card -> barrier goes up-> and so
on....

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
