In $2000,$ Todd was preparing to open his first full size martial arts gym. While he still wanted to spend at least half of his time training clients and teaching classes, as owner, Todd also became the facility's general manager, responsible for over$-$seeing all of the functions of the business.

Three weeks before opening, Todd hired all of his staff, including:

$2$ front desk staff;

$2$ assistant managers;

$1$ facility maintenance staff member;

$6$ martial arts instructors;

$4$ personal trainers; and

$2$ marketing co$-$op students.

From his experience, Todd knew which skills were needed in each of these positions to ensure the success of the gym, including the quality of its classes, atmosphere, and the overall training experience. But how should Todd organize his staff?
