In this case study we describe a four-step process for eliciting and analyzing user behavior with products over an extended period of time. We used this methodology for conducting a comparative study of two mobile applications over a period of seven months with 17 participants. To focus the discussion, we are concentrating on the methodology rather than the results of the study.
