D and E worked as retail sales-operations leaders. Their careers involved a variety of skills from operations
to marketing to workforce management. As executives, they had the ability to see into the operations of retail businesses. They noted a very big problem–scheduling.
Most retail businesses sit down to write their schedule with hopes, guesses, and maybe a set of dice. Deciding which employees to schedule, when to schedule them, and how many employees to put on a given shift is hard when one has no idea how busy the shift might be.
Underscheduling could be costly in terms of unhappy customers and a damaged reputation. Overscheduling could be costly if the price of labor exceeds the sales profit.
