Use Case

Use-Case Model Elaboration Phase

Introduction

This is an example of a Use-Case Model as it would appear in Elaboration. Primary actors and use cases are identified, and key scenarios (those that will be implemented first) are detailed. Each use case has an associated use-case specification.

Overview

The internet banking transfer is a remote unit connected to the bank computer systems. The purpose of the system is to bring regular bank services closer to the customer and increase the working hours to around the clock. It is also important to decrease the amount of bank cashiers. An wire transer is less expensive for the Bank than a withdrawal from a teller. The on line wire transfer system requires that each bank customer has an online accounbt access and remembers his PASS code. The whole security of this system builds on the PIN code.
