SYD366-Sales and Scheduling Test Solved

Part 1: Sales

 

Case Study

 

ProTKD Tae Kwon Do first opened their doors in 2001 at what now serves as their current head office in Thornhill, Ontario with the original business plan of offering Tae Kwon Do classes to children.

 

Business is booming as parents recognize that their children require regular exercise routines.  ProTKD Tae Kwon Do was rebranded and ProTKD Martial Arts and Fitness last year.  ProTKD now offers classes across the Greater Toronto Area, utilizing space in both their owned facilities and community centers.  Classes are now offered for adults as well as children.

 

New families must first enroll with ProTKD as children cannot be added to a class unless the ProTKD is able to contact parents on an emergency basis.  Once enrolled, parents are able to register for classes and purchase items at the ProTKD store.
