TOC, lean, and six sigma: An integrated model to increase the productivity of the textile industry

Facing an ever increasingly competitive market, manufacturing companies, including textile companies, must make changes to improve their operations. In this study, an integrated framework for increasing productivity has been developed by combining six sigma, lean, and Theory of Constraints (TOC) method. This integrated model shows a step-by-step guide using the original methodologies from each discipline and illustrates how those methods can complement each other to improve performance. The integrated model of TOC, Lean, and Six Sigma approach combines waste elimination, evaluated constraint, and continuous improvement technique. A case study of the textile industry (PT. X) implementation is presented.
