The importance of offering quality products that meet customer requirements and expectations, and that are delivered on time has increased considerably, due to the high economic impact of late deliveries, which can cause penalties or even loss of customers. Therefore, delays in production processes are a problem that many manufacturing companies face, either due to poor distribution, disorder or lack of cleanliness in the workstations or lack of proper planning. This problem occurs frequently in the metal-mechanic sector of the country, due to the absence of controls to mitigate problems in the production lines. This research was applied in an SME of the metal-mechanic sector dedicated to the manufacture of parts for industrial mills. The tools used for the proposed solution is the standardization of work to reduce the current production time and improve the plant layout; and the application of material planning. The proposal achieves a reduction in product delivery time, which would avoid penalties and will have a better relationship with customers, increasing the company's profits by 45%.
