Improving Processes Through the Use of the 5S Methodology and Menu Engineering to Reduce Production Costs of a MSE in the Hospitality Sector in the Department of Ancash

The purpose of this document is to improve inventory management processes and food processing at a restaurant in the region of Ancash by applying the 5S methodology and using specific indicators for the location and type of work. All this was achieved with the implementation of the menu engineering methodology, which consists basically of forecasts, linear programming, long-term orders, and inventory management. The proper operation of the new processes was experimentally validated. First, the main results were that the use of approximately 4.30 m2 of the work space allocated to unnecessary activities within the work area was optimized, increasing the number of processes that a worker can perform without moving more than 1 m from their work position. Despite the many studies existing on the methodology implemented, there is scarce material that focuses on its application in restaurants, as it is normally developed in industrial areas.
