Resumo
A competitividade no mercado atualmente faz com que corporações busquem métodos e soluções que entreguem com mais qualidade e excelência seus produtos para os clientes. Este trabalho trata-se de uma aplicação prática da metodologia Lean Seis Sigma em uma indústria do ramo automotivo, identificando problemas e oportunidades de melhorias. O projeto é desenvolvido por meio das fases do DMAIC, em conjunto com ferramentas Lean Manufacturing, como Diagrama de Pareto, Ishikawa, SMED entre outras. Foi identificada elevada perda de produtividade por setup na linha produtiva estudada e definidas algumas causas raízes para o problema: falta de treinamento e padronização das atividades, equipamentos e instrumentos de medições deteriorados e, a partir disso, ocorreu implementação de melhorias. Os resultados mostraram um impacto positivo na produtividade, comprovando a eficácia da filosofia Lean Seis Sigma no setor automotivo. Por fim, foram listadas algumas dificuldades e sugestões encontradas nas etapas do DMAIC para trabalhos futuros.
Nowadays, the competition on the market makes products to be offered with methods and solutions that seek more quality and excellence for customers. This work is a practical application of the Lean Six Sigma methodology in an automotive industry, identifying problems and opportunities for improvement. The project is developed through the DMAIC phases in conjunction with Lean Manufacturing tools, such as Pareto Diagram, Ishikawa, SMED and others. A huge loss of productivity was identified in the setup line studied and root causes were defined for the problem: lack of training and activities standardization, deteriorated equipment and measuring instruments and from that implementation of improvements. Results show positive impacts on productivity and proving the efficiency of Six Sigma in the automotive sector. Finally, difficulties and opportunities found on DMAIC phases were listed as suggestions for future projects.
