For the past several months, I've been working with the CHIRP Radio volunteer tech team to design a mobile solution that allows station DJs to plan out their weekly shows. At a high level, a DJ should be able to browse and select songs from a massive music library, and add them to one or more playlists, which can be used for their shows. The app also has functionality like the ability to read album reviews, view recent activity by DJs in the app, and review a DJ's profile.
A site map is an important artifact when designing any application or website. It shows how the overall navigation should be structured, can be used with end users to validate the taxonomy, and is helpful for developers as a companion to wireframes or mockups.
Below is a site map I recently created for the project. The highest level navigation options are lighter in color, while as the user navigates deeper, darker colors are used to represent those options. The coloring isn't necessarily a known best practice, but something I used to visually suggest the depth of the taxonomy.
A next step in the process would be to create user flows, which illustrate the interaction between the users, the UI, and the system in the context of some of the major use cases for the app.
