General Diary studies and the potential to capture decisions as they happen
As an online grocery store, we often wonder what happens in the exact moments people make a decision. What makes you spontaneously add something to the shopping cart? Why do you decide to buy ingredients for three dinners instead of four? To get closer to what happens in these moments, we combined diary studies with interviews. Participants recorded short video diaries after each shopping trip. Later, during the interviews, we could revisit specific moments and trips they had shared with us, using them to better understand not just what happened, but why.
This presentation is about why we needed this specific method, what made the diary study actually work (as a team, we all had a few unsuccessful diary attempts under our belts), and the things we definitely hope to do better next time.
