[en] With the moving years, the requirements of the environment at the political, economic and social level have been increased and influenced the behavior from the market; this has forced firms to be in constant change and offer products at lower cost in the shortest possible time and with the desired quality. From this perspective, it has been developed a lot of theories, among them the Toyota Production System, which is applied in the majority of companies and gives as a result greater responding capacity to the business, so the best result is obtained in qualitative and quantitative terms; for those reasons that concept is intended to be applied in the case study. The project is focusing on one of the pillars of the Toyota Production System called "kaizen" which means to change for the better, eliminating all kinds of waste; being this, the philosophy that follows the lean manufacturing, by the other handthis study will also consider other improvement techniques. Therefore, a complete analysis will be done of the company "Foundation Lantegi Batuak" and it will be focused on one of the workshops of which it is composed, but also its facilities and activities that carries out in order to finally focuson the specific context of implementation (boiler section). The aim is to perform an analysis of the value chain of the section, in order to standardize the times of each of the stages and reduce the lead time, therefore a flowchart will be developed with the corresponding timings which will be later captured in a current VSM and with the improvement techniques learned, a future VSM will be built later eliminating all sorts of waste
