Abordagem Lean Six Sigma aplicada ao planejamento e controle da produção: pesquisa-ação na construção civil

Abstract

The Construction Industry, essential for the economy and job creation, faces challenges in operational planning and control, with little adoption of methodologies such as Lean Six Sigma. This dissertation aimed to implement and evaluate the DMAIC methodology (Define, Measure, Analyze, Improve, and Control) in two construction companies to improve the process of planning and controlling production. Using the Action Research approach, the DMAIC methodology was applied in a real scenario to identify flaws and propose improvements. The applications achieved the established objectives, indicating that the application of DMAIC in construction is feasible. However, the research points out difficulties in data collection and maintaining information flow, which directly affected the ability to measure and analyze, essential for the advancement of the subsequent phases of DMAIC. The organizational culture did not favor risk analysis or the implementation of performance indicators, which posed a challenge for sustaining improvements. In conclusion, the study emphasizes that the effectiveness of DMAIC in construction critically depends on the qualification of managers, the use of appropriate technologies such as ERP systems, and the effective involvement of the entire operational chain in the planning and control process. The adoption of practices that strengthen the culture of monitoring and data management is recommended, such as the use of dashboards and the standardization of processes and materials, to facilitate implementation and customization according to project needs.
