What metric is used to determine prep levels at Five Guys?

The metric used to determine prep levels at Five Guys is the store sales mix and forecasted sales. This is important because the sales mix gives insight into which products are selling well and which are not, allowing the management to adjust prep levels accordingly. By analyzing forecasted sales, managers can predict demand for specific items and ensure that the kitchen is adequately stocked to meet that demand without overpreparing, which helps to minimize waste.

Additionally, understanding the store sales mix helps staff to focus on preparing the items that contribute most significantly to revenue, ensuring efficiency during busy times. This approach not only enhances the customer experience by reducing wait times but also maintains product quality, as items are prepared fresh and in accordance with customer demand.
