Phase 1: Understanding Requirements

• Understanding what the customer needs very well.
• Ask the Customer about details if it's exist.
• How to write Use Cases:
  • Clear Value:
    Every use case must have a clear value to the system. If the use case doesn't help customers achieve their goals, then the use case isn't of much use.
  • Start and Stop:
    Every use case must have a definite starting and stopping point. Something must begin the process, and then there must be a condition that indicates that the process is complete
  • External Initionators:
    Every use case is started off by an external initiator, outside of the system. Sometimes that initiator is a person, but it could be anything outside of the system.
