Assumptions
Pre-conditions
Use case description
Use case initialization This use case starts when…
For example:
  1. Requested: on demand
  2. A system event occurs: order cancelled
  3. A point in time arrives: midnight on the last day of the month
Use case dialog
Use case termination
Post-conditions

See if you can find an error or something missing from our use case diagram. Very often, taking a closer look at one aspect of the problem will reveal new insights to update existing models. This is a normal and desirable part of the modeling process.
