Scenario+3


 * Scenario 3 **

Jessica is a student of University of Toronto and studies CCIT. Today, she has an important group meeting for the final project of the course at 6:00 pm. Tiffany, Jessica's friend, is a group member of the same group with Jessica and they live close to each other. So Tiffany decided to give Jessica, who does not have a car, a ride. Then, Tiffany set to pick up Jessica at 5:40 since it takes about 20 minutes to get to the meeting place from Jessica's home. Jessica lives in apartment and it usually takes no longer than 5 minutes to get to the ground from her floor by elevator. So she pressed the elevator button at 5:35 and waited for the elevator to come up. However, the elevator is still not coming up for 10 minutes because it stops at several floors before stopping at her floor. And 10 minutes later, finally, the elevator came up, and it was 5:50 when she came down to the lobby. Jessica made Tiffany to wait for ten minutes in front of the lobby. And that is another problem by lateness because front of the lobby is a fire route, which means that cars cannot stay there. So Tiffany had to move around and around the apartment until Jessica comes. Because of waiting for the elevator, Jessica really feels sorry for Tiffany, and other group members, too. Also, she feels bad for wasting time; she has to spend 10~15minutes for nothing.

**MoSCoW Approach** **Must have:** Installing the elevator buttons inside of each suite. -> People do not need to wait in front of the elevators

-> The elevator do not open when nobody is waiting for the elevators, or the elevator is already full. (Sometimes, people press the button and just leave the elevators for personal reasons. In this case, stopping and opening the elevators is wasting time)
 * Should have:** Installing sensor in front of the elevators

-> Users can reservate the elevator at the time they need
 * Could have:** Elevator reservation system

-> It allows elevators to move quickly (three times faster than normal -> can be dangerous)
 * Want to have but won't have:** High speed elevators
