Integração de Lean Six Sigma e metodologias ágeis na indústria química: uma revisão bibliográfica sobre sinergias e impactos em melhoria contínua

Abstract

The continuous pursuit of operational excellence, quality, and innovation in the chemical industry has driven the adoption of established continuous improvement methodologies, such as Lean Six Sigma (LSS), combined with more recent approaches like agile methodologies. The integration of LSS with agile aims to unite the disciplined structure and variability reduction of LSS with the flexibility and adaptability of agile, enhancing the outcomes of continuous improvement initiatives. This undergraduate thesis aimed to investigate, through a systematic literature review, how integrating these methodologies can boost efficiency gains, reduce waste, increase productivity, and promote greater team engagement in complex and highly regulated industrial environments. Case studies, scientific articles, and technical publications discussing practices, synergies, challenges, and observed results in the application of these approaches were analyzed. The results indicate that integration contributes to shorter improvement cycles, better alignment with customer needs, and greater adaptation to constant market changes, while also exposing critical success factors and barriers that need to be overcome for effective adoption. It is concluded that the integrated implementation of Lean Six Sigma and agile methodologies represents a promising strategy for industries seeking operational excellence.
