User Feedback

For the interview the potential user was given a summary view of the content model. Each noun and verb was described. Special care was paid to the language the interviewee used to describe how they might interact with the application. Verbs like “scroll”, “tag”, “search”, and “message” came up often. The user was particularly interested in a file management feature whereby he could upload notes and assignments and students could access these via a sidebar. We correctly anticipated that course material access/management would be a desirable feature and built this into our content model.
