Site maps help to identify the structure of Web sites and applications. They can show hierarchies and connections that allow your audience to gain an understanding of where users may locate content. Task flows take site maps a step further by identifying the various courses of action that a user may traverse within a section of the site. Task flows also draw the connections to error states, content, or page views based on decision points throughout the process. When used together, site maps and task flows can provide your audience with a clear picture of content structures and how users may navigate through them.
