 * Scenario 6 **

Isabella, a 18 years old girl, lives in an apartment building and she is baby sitting her neighbor boy 'Teddy' who lives next door. They both live in a same highrise building on 22nd floor. One day, when Isabella was baby sitting Teddy in his house, Teddy asked her to go to play ground with him as he got bored. So they decided to go to the play ground in their apartment area. They got ready and came out from the suite then pressed the button to call the elevator. When they got access on the elevator, Teddy suddenly started to press every single buttons on the elevator as he got excited. This made the elevator to stop on each floors which annoyed Isabella since the elevator operated slowly until it reached the ground due to Teddy's silly mistake. Finally, they came down to the lobby. Isabella looked at her watch, and she realized that it took more than 15 minutes to get to the ground. She wished that she could correct the buttons to "unbuttoned" so that she do not have to waste her time again next time.



**MoSCoW Approach ** __**Must have**__ A correction button; allows to cancel the wrong button by re-pressing the same button

__**Should have**__ A touch pad system; especially for disabled people

__**Could have**__ A voice system; it automatically takes the user to their destination once they say out the floor level

__**Want to have but won’t have**__ Wrong button detector; automatically eliminates the wrong pressed button through the sensor
