The textile industry plays an important role in the global economy; however, it faces persistent challenges related to reducing rework for improving productivity. The purpose of this study is to summarize some scientific researches about production delay caused by rework in a clothing and accessory industry. It provides a general overview of the current state of knowledge concerning the interdependence between reduced productivity and rework rate. The research process is based on the Functional Analysis System Technique. It facilitates a systematic examination of sequential and logical steps necessary to achieve objective and attain outcomes. Functional Analysis System Techniques not only provides a structured methodology but also aids in identifying the successive functions crucial for attaining desired outcomes. The initial phase involves conducting a comprehensive systematic literature review focused on productivity issues stemming from rework within the textile industry. The first phase, related to the Seiri of the 5S methodology, involves conducting a comprehensive systematic literature review focused on productivity issues stemming from rework within the textile industry. Subsequently, the filling of a literature review synthesis matrix using Excel is conducted which represents Seiton. Next, focusing specifically on the Lean tools employed utilized and the corresponding productivity improvements, data are extracted. This corresponds to Seiso step. Following this, a Network Meta-Analysis is applied, representing the Seiketsu. Finally, the identification of the most effective Lean tools combination to reduce rework is undertaken, corresponding to Shitsuke. As results, the Ishikawa Diagram appears to have obtained the best ranking position according to the rankogram. Ishikawa Diagram is often associated with other tools to multiply its performance. The study's findings highlight that the Ishikawa, Pareto, Single-Minute Exchange of Die and Work Study combination emerges as the most effective approach for minimizing rework and enhancing productivity, as indicated by the League Table. This network meta-analysis provides a comprehensive overview of the Lean tools synergy effectiveness in rework reduction and productivity improvement strategies in textile industries. While powerful, Network Meta-Analysis has limitations including reliance on indirect comparisons from studies that may not directly compare all treatments, inheriting biases and complexities, which can pose challenges in assessing result certainty.
