The main goals of this method are:
- understanding the problem space and the context;
- discovering the most frequent use cases and the edge cases;
- getting insight on the users’ habits, motivations behavior and

When conducting diary studies, the first task is setting up a framework: what should be logged by the participants, and when should they log their activities; how often should we contact with the participants; what are the follow-up phases. One of the main advantages of diary studies is that if we ask the participants to send their logs regularly, we can always ask more questions about a specific point or issue. It helps us finding patterns in the users’ behavior, and at the same time we can observe interesting scenarios and use cases.
