There is one Navigation Map per system. The purpose of the Navigation Map is to express the principal user interface paths through the system. These are the main pathways through the screens of the system and not necessarily all of the possible paths. It can be thought of as a road map of the system's user interface.
The Navigation Map serves as a backdrop and a link between the individual Storyboards. The Storyboards describe how the user moves navigates through the user-interface elements to perform system features and the the Navigation Map defines what the valid navigation paths are. The Navigation Map conveys the structure of the system's user interface, and the Storyboards convey the dynamics.
The Navigation Map makes it easy to see how many "clicks" it will take a user to get to a specific screen.
The Navigation Map shows the user interface elements and the navigation paths between them.

Brief Description |
Representation |
---|---|---|
User-Interface Elements | The screens, forms, Web pages, etc. that the user interacts with. The user-interface elements represent the system's user interface. | Depends on the representation selected for the Navigation Map. See the Tailoring section. |
Navigation Paths | The paths between user-interface elements that the user can traverse while interacting with the system's user interface. | Depends on the representation selected for the Navigation Map. See the Tailoring section. |
The Navigation Map may first be introduced during Inception when initial brainstorming on what the system's user-interface should look like is performed. It is refined over time as the user interface for the system is developed and stabilizes.
The User-Interface Designer role is primarily responsible for this artifact. Those responsibilities include:
A variety of representations may be used for the Navigation Map. Some examples include:
The selected representation and any tailoring decisions should be documented in the project-specific guidelines.
