The textile sector, particularly small and medium-sized enterprises (SMEs), plays a pivotal role in the economy by generating employment and fostering innovation. However, these enterprises face significant challenges, including production inefficiencies and quality control issues. Previous research has explored the application of Lean Manufacturing methodologies to address these challenges, yet there remains a gap in the literature regarding comprehensive models tailored specifically for textile SMEs. This study aimed to fill this gap by proposing a Lean Synergy Production Model integrating Change Management, 5S, Methods-Time Measurement (MTM), and Line Balancing.

The textile sector faces urgent challenges such as high defect rates, excessive cycle times, and low productivity. These issues stem from inadequate production methods and poor workplace organization, resulting in increased costs and reduced competitiveness. The proposed model addresses these challenges by streamlining processes and enhancing operational efficiency. The model implementation involved training employees, reorganizing the workspace, optimizing task allocation, and balancing production lines.

Key results from the six-month pilot implementation included a 65.67% reduction in delivery delays, a 23.08% decrease in defective products, and a 27.27% reduction in reprocessing rates. Productivity increased by 84.62%, and cycle time was reduced by 25%. These outcomes demonstrate the model's effectiveness in improving production efficiency and quality in textile SMEs.

The study's impact extends beyond operational improvements, contributing to academic literature by providing a validated model for Lean implementation in SMEs. Socioeconomically, the enhanced efficiency and quality can lead to increased competitiveness and market share for textile SMEs, fostering sustainable economic growth.

Future research should explore the model's adaptability to other sectors and its long-term sustainability. This study calls on researchers and industry practitioners to further investigate and refine Lean methodologies to support the continuous improvement of SMEs globally.
