What tool is used by Publix deli to manage product variety and expiration?

The entrée selling plan calendar is the correct choice because it provides a structured approach for managing the variety of products offered in the deli, including rotation and planning based on demand and expiration dates. This tool enables the deli to schedule which items will be promoted or featured on particular days or weeks, thus ensuring that products remain fresh and minimizing waste due to expiration. By aligning product offerings with consumer preferences and operational capabilities, the deli can effectively manage inventory levels while also responding to customer needs.

The other choices, while useful in their respective contexts, do not specifically address product variety and expiration management. An inventory checklist is primarily used for tracking stock levels, an employee feedback form gathers staff insights but does not pertain to inventory management, and a customer satisfaction survey focuses on feedback from shoppers rather than the operational aspects of managing deli products.
