This paper presents a structured Lean Manufacturing intervention aimed at improving productivity in the sewing line of a Peruvian textile company dedicated to jean pants production. The study follows a three-phase approach: diagnostic assessment using Value Stream Mapping (VSM) and root cause analysis; implementation of 5S for workplace organization and a Poka Yoke system to minimize defects; and validation through simulation using Arena software. Data were collected via time studies, historical production records, and direct observation. As a result of the intervention, productivity increased by 27.4%, lead time was reduced by 19.5%, and the defective rate declined by 28.6%. These findings provide empirical evidence of the effectiveness of Lean tools in small-scale apparel manufacturing and contribute to the literature on continuous improvement in the Latin American textile sector.
