This can be appreciated after the clothes are washed and dried and the study revealed that over 20% of the items were returned each month. This occurs when the acquisition of raw materials is focused exclusively on the price. Thus, there are no requirements for compliance with any technical specifications that would enable the production process to be equipped with quality raw materials. Additionally, the absence of control over the quantity of consumables based on demand generates reprocessed inventory, thus damaging the fabric. Therefore, the proposed model was made through the Lean Six Sigma method to reduce waste and meet client requirements. The results were a decrease in returns by over 16.5% and an increase in productivity by 28.5%.
