Aplicação da metodologia lean seis sigma para a melhoria do sistema de gestão de uma indústria química.

Abstract

ABSTRACT: The present work aimed to evaluate and improve the management system of a chemical manufacturer by implementing the Lean Six Sigma methodology. Actionresearch was used to elaborate this work and the DMAIC methodology was used to design the project. The root causes of non-conformities from the company's internal audit were identified, the open non-conformities in the system were analyzed one by one with the responsible sectors leaders to determine the best deals or evaluate their effectiveness. A map of the current state of the process of opening and creating nonconformities was also drawn up, where waste points in the process were identified, which made it possible to design the future state map with optimized steps and performed automatically due to the systematization of the process. All the actions of the project were due to the use of quality management tools widely used in Lean Six Sigma, such as SIPOC matrix, value stream mapping, Ishikawa diagram and 5 Whys. As a result, it was possible to reduce by 59.23% from the total pending open in the system, in addition to a reduction of 54.76% of non-conformities from the internal audit within the sectors analyzed. Finally, it was possible to simplify and systematize the process of opening and creating non-conformities, allowing steps to be performed automatically.
