Element Scenarios & Requirements

The Scenarios & Requirements window provides a convenient method of quickly adding, viewing, editing and deleting rules applied to an element. The window shows details of the entities that impose such rules or restrictions on the element, namely:

  • The element's scenarios
  • The element's internal constraints (not external Constraint notes)
  • The element's internal responsibilities or requirements

Use of the window

The Scenarios & Requirements window is typically used to examine Use Case and Test Case elements, and any other elements that realize an external Requirement.

For convenience, you can display the window as either a dockable window around the edge of your workspace, or as a view in the center of your workspace (in which the Scenarios, Constraints and Requirements are shown on separate tabs).

Use the icon in the window toolbar to toggle between these display options.
