Using information from the case study description above, create a Use Case diagram for VIP-Ghana
Transcribed Image Text:CASE STUDY
VIP-Ghana is a transport company based near Awudome in Accra. They specialize in
organizing day trips to various destinations in Ghana among other routine transport operations.
Customers of VIP-Ghana include institutions such as schools, government agencies, district
assemblies, nursing homes etc. They hire buses with drivers for trips which are
organized/arranged especially for them.
The manager of VIP-Ghana is responsible for allocation of buses and drivers to trips. Trip
records are created when trips are arranged. If a customer (for whom a trip is being arranged)
is 'new' then the customer's details are recorded. Otherwise, the customer's record is updated.
Customers will typically request that a day trip be organized for them on a specific date. The
number of buses allocated to a trip depends on the number of seats required. In response to this
request VIP-Ghana will check to see if the required buses can be made available on that date.
If the buses are available VIP-Ghana will allocate one or more drivers and create a trip record
for the customer.
Customers are allowed to cancel a trip before a deposit is paid. The deposit should be paid
within 7 days of the booking for the trip being taken. If a trip is cancelled after that, the deposit
is kept by VIP-Ghana. If a trip is cancelled the trip record will record this.
VIP-Ghana will request full payment for a trip in the week before it takes place. A cancelled
trip is deleted from the system 6 months after cancellation. Other trip records are deleted 12
months after the corresponding trips were completed.
