Abstract

The studied company offers its clients a first quality and fast assembly house. Its dispatch and delivery depend on the production phase of the prefabricated elements and the final assembly phase of the product. The goal of the research is to find the existing waste in both phases mentioned, through the application of lean tools. For this purpose, a visual analysis of the current operation managed by the prefabricated company was conducted. The data obtained allowed the calculation of productive and unproductive time and the classification of activities that add value (AV) and do not add value (NAV); for a clearer vision of what happens within the processes, a value stream mapping was developed. Current VSM where the existing waste is distinguished gave way to the search for tools that help reduce or eliminate said waste, which were chosen with the help of lean experts considering the type of waste and the setback that generates it. From this analysis, in which the errors in the processes were found, strategies were set up to improve them and the future VSM was proposed.
