Requirements

You use the Requirements page of the element Properties dialog to create requirements that this element is designed to meet.

Requirements are of two types:

  • Internal requirements (responsibilities) and
  • External requirements (system requirements, elements connected to the element by a Realize connector)

Enterprise Architect shows both types, but you can only edit the internal type from the Requirements page.

You can show the requirements for an element on the diagram directly, using the Feature Visibility function; it is also possible to show inherited requirements in this way.
