The investigation was carried out in the workshop area of the company GIANT IBARRA, whose main problem is the delay in the delivery of finished bicycles causing a breach of the demand requested by the commercial area. This reason influences the proposal of an improvement within the production process, which allows a decrease in productive time, guarantees efficiency, and reduces the use of resources that do not add value to the process through the application of tools of the Lean Manufacturing methodology. The development of the proposal required the design and description of operational tools such as 5'S, Kanban, and Manufacturing Cell; for the latter, the new working method that will increase efficiency was determined. Through the Value Chain Map (VSM) tool, it was possible to obtain the results of improvement based on certain indicators, where a decrease in lead time of 27.55 minutes is observed; on the other hand, the production capacity is increased to 27 bicycles generating an efficiency increase of 8.05%.
