The textile sector in Peru has been growing over the years. This growth has generated an increase in the production of textile products, standing out among international markets for the quality of products and fibers used in the country. Indeed, textile companies mean a lot for the country's economy, so it is important that these companies produce textile products in the most efficient way and can be competitive in the international market. Therefore, this research seeks to improve the efficiency in the cutting area of a Peruvian textile company. As main problems of the low efficiency of the company in the cutting area, problems such as poor preparation of activities and an excess of time in the replenishment of materials were found. In order to solve this problem and reach a level of 90% efficiency in the area, the use of Lean tools such as SMED and Work Standardization was proposed. These allow a better time management and level of preparation for the operations in the area. Also, Arena software is used to simulate the current model and the improvement proposal. The situations are compared, and the margin of improvement is identified after the application of the tools.
