  2. Purpose of the System • Simplifies existing chat program concepts adapting • them for use in inter-corporate communication (AOL • AIM, Yahoo Instant Messenger). • The ICS system allows corporations the ability to • restrict one-to-one communication to their local area • network (LAN). Scope of the System • The internal components of the ICS system are the server and the client programs. • The ICS users are the actors involved with the use cases and are outside the boundaries of the system.

  4. Functional and Non-Functional Requirements Use Case ID: ICS01 – Log In Scenario: Actor: ICS User Pre-conditions: 1. ICS server & chat client process must be running. Description: 1. Use case begins when the Log-in window pops open and requests the user’s name and password. 2. The use case ends when the login is successful and the user’s client contact list window is displayed.
