Prior to the interviews, a pre-survey was conducted over 8 days, targeting 177 Gen Z participants. Based on the pre-survey results, a group of 30 individuals was recruited for face-to-face interviews, which were carried out over a span of three days. The interview format involved a modified version of a Focus Group Interview (FGI), where two interviewees engaged in a conversation, exchanging responses of questions . Each group session lasted for 15~30 minutes. These interviews aimed to gather insights on the prioritization of camera app features through card sorting, understanding user's smartphone camera usage patterns in terms of photo and video editing, and exploring Gen Z's perception of Samsung cameras. I actively participated as an additional interviewee, examining Samsung phone features and engaging in discussions with other interviewees. The interview findings were grouped according to users' journey map and presented along with the final insights.

Each team member conducted ideation sketches for 10 scenarios based on user journeys, resulting in a total of 140 feature ideas. These ideas were then subjected to a first-round internal evaluation, where they were assessed and categorized as high, medium, or low priority. In a second-round meeting and discussion, similar ideas from the first round were integrated, and existing ideas were further developed and evaluated. Ideas that advanced to the final evaluation underwent an online assessment, leading to the selection of 30 final feature ideas. Based on these 30 ideas and the interview results, we derived three user personas.
