Appendix C: GreaterCause Site Flow

The navigation semantics of the UI illustrated in Appendix B is explained using a site flow that clearly articulates the page transitions associated with user actions. The site flow is an important artifact for articulating the navigation semantics and provides a bird's-eye view of the site. Site flow does not encompass each and every navigational aspect because doing so will make it less readable. To avoid the clutter, a common technique used for creating site flows is to draw it like a tree structure where every node has only one parent. The site flow will complete the story boarding effect by showing the transitions between various uniquely numbered wire frames according to the navigation semantics established for the functional web site.
