Use Case Name 001 Customer Registration

Use Case overview Customer enters the site and asks for the registration

page. Once presented with the page, Customer enters

the requested information and submits it. A credit check

is performed on the customer. If the credit rating is

acceptable, the Customer Management service is

invoked to register the customer. The appropriate

Delivery services, as selected by the customer, are

invoked to assign account numbers. On completion, an

e-mail is sent to the Customer indicating the status of

the registration (success or failure). If the registration is

successful, the account number or numbers are

returned.

Preconditions The Customer supplies the information required to

create a new customer account and selects one or more

account types (business, home, or both).

Termination Outcome 1 The Customer Management service registers the

customer, creates the appropriate accounts, and sends

a confirmation e-mail.
