Abstract: The lean manufacturing seeks to ensure the quality of the service and the supplier’s products by the companies that implement this methodology, through the improvement of the research environment and the elimination of the classic wastes present in any process. The research was developed in a metalworking company which presents as main problem the delay in the delivery of the finished product (rolling doors), generating complaints and nonconformities. For this reason, the need arises to make a proposal for improvement in its production process which allows to reduce the delivery time of the product to its customers and to guarantee its efficiency and productivity, using the tools and techniques of lean manufacturing. The methodology assumed in the study, corresponds to the philosophy of lean thinking to develop an improvement proposal where the following tools were used: value stream mapping, 9’S, single minute exchange of die, total productive maintenance, Kanban which provided the following possible results: total production process time would improve by 6.10%, value added time by 2.13%. The production increases from 24-26 doors per month, giving an improvement of 7.4% and mainly, the delivery time would decrease 590-554 min with a reduction of 6.10%, all these results lead to faster and more efficient deliveries to the customer. A case study was carried out in the metalworking company in Ibarra, Ecuador. The results also indicate that lean thinking contribute substantially to the operating performance of company is decreased about 7% of the time in operational performance.
