Lean manufacturing diffusion analysis in the Itajaí Valley: A multiple case study in textile enterprises

Abstract

Efficiency and competitiveness are constant for companies, especially in the textile industry. In this context, the application of lean manufacturing tools allows optimization of production processes and improvement in products quality, thus achieving positive outcomes. With that in mind, this study aims to diagnose and analyze the diffusion of lean manufacturing tools in the regional textile sector. It was conducted through multiple case studies in four textile companies from different segments in the Itajaí Valley region, all of which are large-scale enterprises (employing over 500 individuals). A questionnaire was responded by professionals operating at the tactical level, including managers, analysts, and coordinators. The results revealed that the surveyed companies possess knowledge about lean manufacturing tools, although not all tools are effectively utilized, showing there is still room for improvement. This way, future studies are necessary to amplify the sample, create and verify a model to maintain its implementation.
