The textile sector is one of the most important sectors in Peru. Currently, the Peruvian market is highly competitive not only among domestic producers, but also with imports of textile products, which have been increasing progressively in recent years. Therefore, for a textile manufacturing company to be competitive in the Peruvian market, it must not only focus on offering the best price, but also a high level of service that allows it to differentiate itself from other competing companies. In this sense, the use of lean tools such as TPM and 5S integrated with SLP is proposed to improve the service level of a textile SME. To support the effectiveness of the model and the improvement of the critical indicators, the model is validated through a pilot test and simulation. As a result of the application of the model, an increase of 25% in OTIF, 13% in overall equipment efficiency, 11% in production and reduction of 34.57% in search time were obtained.
