Optimization Model Applying Lean Six Sigma for the Reduction of Time in the Granting of Authorization Titles for Mining Projects

According to the Ministry of Energy and Mines (2024) in 2023, the mining sub sector represented 10.4% of Peru's Gross Domestic Product (GDP), while in 2024 exports of key metals (silver, copper, lead, zinc) reached US$ 3,104 million. In January 2024, mining investment amounted to US$ 441,703,467, 61.9% higher than the figure recorded in the same month of the previous year. These indicators confirm that mining is essential for the Peruvian economy, representing one of the main sources of income and generating direct and indirect employment. As a world leader in the production of copper, gold and silver, Peru occupies a strategic role in international markets. However, the long times in granting authorization titles for mining projects affect the competitiveness of the sector and the attraction of investments. This research addresses this problem by applying Lean Six Sigma tools to optimize administrative processes, reduce operating costs and accelerate project execution. Improving efficiency in the Mining Concessions Department will strengthen Peru's position as an attractive destination for mining investment, especially in a context of growing global demand for minerals. Therefore, the results of this study contribute to the sustainability and competitiveness of a crucial sector for the national economy.
