A integração do Lean Six Sigma na indústria: as principais dificuldades encontradas conforme revisão integrativa da literatura e a aplicação de oportunidades e melhorias para otimizar resultados

Abstract

When considering the constant evolution of the Industry's procedures, standards and production, it is necessary to pay attention to the strategies that allow listing the gain in values with the reduction of waste, improving quality and productivity. Thus, in seeking to eliminate defects as much as possible, emphasis is placed on the Lean Six Sigma (LSS) methodology, which encompasses quantitative management strategies to increase and enhance these gains. In this context, the general objective of this work was to list possibilities for improvements to difficulties pointed out in the literature with regard to the integrated implementation of the LSS. To this end, a qualitative study with an Integrative Literature Review was used to synthesize findings on the main difficulties for the implementation of LSS in Industry, based on articles published between 20182023, also using Research Prism Figure. The results pointed to 10 articles that allowed the grouping of these difficulties into 7 thematic units: lack of technical training of professionals, communication and relationship failures, disregarding customer opinions and feedback, poorly designed and managed projects, waste of materials, equipment and materials of low quality and the need for Constant calibration of machines and equipment. From this data collection, it was possible to list the importance of seeking solutions for each of these difficulties, also pointing out the possible quality tools that can be used individually or in combination. After highlighting these suggestions, the need to maintain control of these established improvements was also related, aiming at effectively achieving the goals and objectives achieved, giving continuity to the results.
