Exercise

• A travel agency organizes trips. To organize a trip the

following tasks are executed.

• First the customer request is registered, then an

employee searches for opportunities which are

communicated to the customer. Then the customer is

contacted to find out whether (s)he is still interested and

whether more alternatives are desired.

• If the customer selects a trip, then the trip is booked. In

parallel (if desired) one or two types of insurance are

prepared.

• Two weeks before the start date the documents are sent

to the customer.

• It is possible that the customer cancels the trip at any

time before the start date.
