The main objective of this research is to determine how the Lean Manufacturing methodology influences the improvement of productivity in the book production process.Due to the fact that, in the printing press, there are inefficiencies in the production processes such as disorder and dirt throughout the workshop, excess inventory and its high residence time, very high setup times in the printer and high% waste and highlead time. All these problems lead to low productivity performance, which is what isbeing sought to improve through Lean tools to address the problems mentioned.According to the current Process Flow Chartof book manufacturing, there is a productivity of 41.83book/man-hour.In addition to observing other waste such as checks, waits, transfers and movements.By using the current VSM, it was possible to determine the wastes of inventory, low % value added and a high lead time. To first attack the disorganization at the work area by using the 5Sand the lack of coordination among the processes by means of Kanban. And then attack the bottleneck (printting process) by using SMED and TPM.Finally, obtaining as results a cleaner and tidier area, reduction of the inventory level by 90.73% throughout the workshopand increase % of added value by 36.10%. In addition to achieving a reduction in setup time of 58.85% and a reduction of Scrap% to 1.5% in the printting process.Theseresults are shown by the future VSM andtheproposed Process Flow Chart, indicating a reduction in time and inventory, which generated a productivity of 56.42book/man-hour (improvement of 34.88%). With a feasible work plan, backed by an economic-financial analysis that yielded a NPV of S/. 110,783.33and a IRR of 120%in a pessimistic scenario.
