A use case typically includes the following information:

• Name: The name of the use case
• Brief Description: A brief description of the role and purpose of the use case
• Flow of Events: A textual description of what the system does in regard to a use case scenario (not how specific problems are solved by the system). Write the description so that the customer can understand it. The flows can include a basic flow, alternative flows, and subflows.
• Key scenarios: A textual description of the most important or frequently discussed scenarios
• Special Requirements: A textual description that collects all of the requirements of the use case that are not considered in the use-case model, but that must be taken care of during design or implementation (for example, non-functional requirements)
• Preconditions: A textual description that defines a constraint on the system when the use case starts
• Post-conditions: A textual description that defines a constraint on the system when the use case ends
• Extension points: A list of locations within the flow of events of the use case at which additional behavior can be inserted by using the extend-relationship

You can document the use case as a use-case specification document or you can incorporate the use case in a use-case model. You can also use a requirements management tool to capture use cases and parts of use cases.
