Week4. In this week studio we all focus on event analysis and use case narratives. Beacuse this will be our first assignment need to hand in. There are many arguement and different opinion during the disscussion. And after the disscussion we sprate into 2 groups, 1 group is focus on developing the assignment and the other group is working on the presentation, which we are going to deliver next week. I think all members in our group decide to do better this time. So, everyone are working hard and give different suggestions for the presentation.
