Ball Ride-Group 5
Ball Project Problem Statement/Objective
Riders’ complaints have increased by 10% from the previous waterpark season, due to the lack of time spent on the ride. This is in contrast to the 2% of complaints filed during the previous season.
Enhance the customers experience by increasing time spent on ride. Thereby decreasing complaints 5% by the end of the next waterpark season.
