3. Pre-lecture exercise [can do in pairs] : Imagine you are building an online system called TeamFormer. Specify the vision, scope, user types, and the workflow of TeamFormer. Specify requirements of TeamFormer as a list of User Stories. TeamFormer is a system for helping CS2103 students during team forming period. It lets students record who is in which team. Students can use the system to find teams short of members and students looking for teams, easing the team forming process. Note that the system is not meant as a platform for students to communicate with each other to find team members. Students are supposed to talk to each other and form teams outside the system, as they do now. TeamFormer simply helps students to see the team forming status of the class (e.g., who has teams and who doesn’t) and record their own team after forming a team. It is also meant to ease the team-forming-related workload of instructors. If you didn’t try this exercise earlier, try it now. If you have any questions, come down and talk to me now.

Vision: Scope: for CS2103? for NUS? for any school? for the world? for capturing team forming status ? to form teams using system? Users: instructor, student, Workflow: (a) Any student can create/join/leave any team? (b) Instructor creates slots and leader sign up for slots? To make team forming easier
