2. Exercise: 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 that lets CS2103 students keep track of the team forming status. During the process of forming teams, students can use the system to find teams with a shortage of members or find students with no teams. Students can also use the system to record their own team after forming one. In a way, it eases the team-forming-related workload of instructors. However, the system is not meant to be a social 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. Try this exercise... 77577 OR tinyurl.com/answerpost feed2103 blah blah..

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

11. Use case: add student to team Actor: Instructor Pre-condition: Logged in MSS: 1. Instructor chooses student to add 2. System shows teams that can take the student 3.

Interactions, not UI design Can be different from yours
