This study was developed in a furniture company and aimed to implement some Lean tools, such as 5S and Visual Management to reduce waste, by improving the production process. To carry out this analysis an observation plan was used, having the Spaghetti diagram as a reference as well as the value-added analysis of the operations. The implementation of 5S’s allowed the improvement of the visual management and the organization through a reorganization of the layout, as well as normalization of the production process. With this, a reduction of 40% was achieved in terms of waste related to activities that did not add value to the product, such as unnecessary movements, waiting times and even movement of materials, having achieved a level of productivity of 74% and 87% in the finishing and joinery sections, respectively. In addition to improvements in the production process, the impact of the measures at the safety level (lean safety) was assessed. For this purpose, a questionnaire was prepared to assess the opinion of the employees, in which 40% considered that the implementation of the tools provided a greater motivation to develop their work activities safely.
