Scenario+8


 * Scenario 8 **

Sunny had an appointment with her family doctor for health examination. When she got on the elevator, the elevator became full so no more person could get in the elevator. However, as the elevator goes down, it continuously stopped on several floors, but nobody could not get in so people in the elevator had to waste their time on stopping and waiting for the opening and closing of elevator for no reason. This was really annoying for the people in the elevator, especially in busy hours.

**MoSCoW Approach** **Must have:** Installing outside sensor system -> the system detects that nobody is standing in front of elevator, the elevator skip the floor.

-> If the elevator is already full, the elevator does not stop at the floor even though the button was pressed.
 * Should have:** Installing inside sensor system

-> If people press the button and change their mind, they can cancel the button.
 * Could have:** Correction button


 * Want to have but won't have:** Installing more elevators in the building
