Lean Six Sigma-Driven Enhancement of Fabric Production at Dominican Knits: A Case Study in Reducing Rejection Rates

In the competitive landscape of textile manufacturing, Dominican Knits confronts the challenge of excessive fabric lot rejections. This study delineates a Lean Six Sigma-informed intervention, utilizing the DMAIC framework to systematically diminish defects and augment production efficacy. The research encapsulates a fusion of Lean Manufacturing tenets and Six Sigma precision, fortified by FMEA and Statistical Process Control to dissect and rectify process inefficiencies. A meticulous research design underpins the investigation, employing empirical data collection and robust statistical tools to excavate the root causes of quality lapses. The diagnostic phase uncovers pivotal shortcomings within the dyeing and finishing processes, catalyzing the development of a comprehensive improvement strategy. Subsequent hypothesis testing and statistical scrutiny validate the efficacy of the proposed enhancements. The culmination of this study is a strategic control plan, crafted to perpetuate the gains achieved and to institutionalize a culture of continuous quality advancement. The findings articulate a persuasive narrative for Lean Six Sigma's integration into textile operations, projecting not merely incremental gains in process performance but also substantial strides in organizational profitability.
