Proposta de um framework de implementação do Lean Six Sigma baseado no DMAIC para aplicação em micro, pequenas e médias empresas

Abstract

In this study, we explore the implementation of Lean Six Sigma, focusing on the DMAIC process, within small and medium-sized enterprises (SMEs) – a sector often constrained by resources but essential for economic dynamics. The purpose is to demonstrate that DMAIC, a tool traditionally linked to large corporations, is equally valuable for SMEs when addressing operational inefficiencies and chronic problems faced by this segment. Using qualitative methodology, including an analysis of specialized literature, we reveal how DMAIC can be customized and effectively applied in contexts where flexibility and innovation are indispensable as competitive advantage. The research indicates that SMEs can incorporate DMAIC to significantly enhance quality and efficiency of their processes, despite implementation challenges that include data scarcity and cultural resistance. We propose practical solutions, such as the development of managerial skills and the promotion of a culture of continuous improvement, especially among IT managers, who are critical to the success of the methodology. This work not only argues for the adaptability of Lean Six Sigma to SMEs but also provides a pragmatic guide for its operationalization, contributing new insights to the field of process and project management.
