title: Include or Extend Use Case Relationship?
body: <p>I can't figure out which relationship I should use in my use case. Let's say the actor is User who can Manage account:-Create; -Delete; -Update;</p>
  
  <p>Any ideas whether I should make Manage Account as a use case and then link Create, delete, update to it - if yes - extend or include relationship? Or it would be better if I leave as separate use cases Create, Delete, Update?</p>
