Currently, the Peruvian textile sector, especially the MSMEs and SMEs, is affected by several factors that have lowered its productivity level. In fact, this industry is already dealing with difficult markets for the high level of competitiveness and informality. For this reason, it is very important to counteract these factors internally affecting the companies' operating processes. Most companies, with the intention of lowering costs, seek to hire personnel with a certain level of experience, since it is assumed that they would support them in carrying out the work in their position, meaning that the personnel hired are not trained to perform their tasks. Likewise, maintenance is minimised or non- existent, and plants are not properly organised. All these factors result in a decreased level of productivity. This paper seeks to demonstrate that regular training, planned maintenance and proper plant layout will result in the reduction of the negative effects mentioned above. For this purpose, there are certain tools available that will be mentioned in this article, such as SLP, Autonomous Maintenance and/or Planned Maintenance (TPM), Poka Yoke and Standardised Work, as they will be implemented for intervention in the production process in a company aimed to manufacture sleepwear, where an increase of 14% in their productivity level was achieved.
