The entire event revolved around trust. Based on this, we created a slogan, “We believe in you”, and we reinforced it with a song, “Believe”. We also made all participants use the app that we had designed to answer the question “Why can you trust me?” before the event. Prior to the event, we prepared the various newsletters, the app with information about the day, the sizes of the shirts, gamification, and scoring questions. On the day of the convention, the group carried out three activities focusing on the area of trust and having fun. Lastly, we designed a golf tournament for all participants, regardless of level.
