Abstract. Today, the accelerated development of industry 4.0 and the immersion of technologies with the DMAIC methodology, Lean Manufacturing allows higher productivity and continuous improvement of industrial processes. There are countless manufacturing companies, of which very few have invested in technology and methodologies, so they have not been able to prepare themselves to advance at the same pace as the industrial revolution. This research proposes to include improvements in the manufacture of furniture by applying software tools and methodologies such as DMAIC, which consists of combining the application of some tools such as Lean, visual management, and standardized work. As a case study, we applied to the manufacture of furniture; the results indicated that by applying DMAIC and simulation tools, a significant increase in production was achieved, with a decrease in delivery time, in addition to the optimization and reduction of waste. This research can serve as a reference for future studies related to manufacturing processes when applying DMAIC, Lean Manufacturing, and simulation software. Keywords: DMAIC methodology · Industry 4.0 · Lean manufacturing · Process · Productivity · Simulation · Software

1 Introduction Currently, small and medium-sized enterprises (SMEs) have become an essential source of employment in the economies of countries, and their contribution is fundamental to generating jobs in a more dynamic and competitive environment [1]. The problems in SMEs have related to the lack of 1) organization in the processes; 2) continuous training; 3) implementation of new technologies; and 4) knowledge of those who lead the organization [2]. A high number of companies vary according to the tasks they perform. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2021 M.

The term Lean Manufacturing means fat-free [3, 4], so in the Lean industry and service field, it is agility and flexibility. Lean Manufacturing aims to eliminate all activities that do not add value [5], focusing on process improvements and optimization. In this research, we take as a case study, this methodology to apply in the manufacture of metal furniture. This article proposes, through the DMAIC [6] to identify the process to which the study will be focused, to measure the time of the furniture manufacturing cycle, to analyze the problems employing technological tools such as simulators to 1) identify the problems, 2) propose improvements based on the application of reading t
