Survey

Self-reporting information is extremely valuable. It is also the most efficient letting you reach out to thousands of users at once. However it lacks context so it is often difficult or impossible to discern the cause and effects if surveys are the sole data points. Following surveys up with interviews, or emails helps. Triangulating it with data from interviews and focus groups etc., also help strengthen the quality of the data by bringing some context via alternative complementary data.
