The purpose of this research is to provide a solid and well-founded theoretical framework to optimize the supply system, contributing to the development and well-being of the community in the Cajamarca Region. The proper implementation of this system will improve public management and labor productivity, through improvement strategies in the entity. To achieve this, coordinated work is necessary with the General Directorate of Supply of the Ministry of Economy and Finance, as well as with the State Procurement Supervisory Body. The results are based on a technical study that analyzes 50 scientific articles published between 2019 and 2023, and it is concluded that the supply system is crucial to guarantee an efficient and timely supply of resources in the sub-management of the Cajamarca region. Challenges in inventory management, supplier selection, cost optimization and risk mitigation are identified, but opportunities to improve efficiency, quality and decision-making in supply are also highlighted.
