After user and competitive research, I landed on a dashboard centered approach for the UX. I found that since all the tasks a user needed to perform would be associated with some kind of output, a place to view, edit, and monitor that output should be the centerpiece that the UI revolves around. A simple consistent tabbed table layout was used with taxonomies specific to their respective buckets. From the dashboard, users can quickly branch out to perform other tasks.
The creative editor is modeled after existing image editing programs, using familiar conventions such as drag-n-drop, panels, and stackable lists.
The add device and add campaign tasks use a wizard UX flow to walk the user through the steps that are needed for completion.
