A use case vs a use case model​

A use case model is a set of use cases.

what are use case diagrams used for?​

  • Prioterize requirements.
  • requirements elicitation

  • Architecture defines the form.

iteractive and incremental​

  • Give developers early feedbacks
  • Mimize the risk of developing wrong system
  • Accomdate evolving requirements
