How Lean Management Drives Operational Excellence in Sri Lanka’s Apparel Sector: A Pathway to Competitive Advantage

This study investigates the correlation between lean management practices and operational performance in Sri Lanka's apparel industry, focusing on the significance of continuous improvement, waste elimination, leadership support, and supplier involvement in fostering operational efficiency. Motivated by the severe impacts of an economic downturn on the garment industry, this research underscores the urgent need for effective management strategies to sustain competitiveness. The study adopts a quantitative approach, collecting data through structured questionnaires from a sample of 275 managerial-level employees across 10 major apparel manufacturing companies in Sri Lanka. The sample was selected using purposive sampling, ensuring that participants have direct involvement with lean management practices. The analysis reveals that continuous improvement, leadership support, and supplier involvement significantly enhance operational performance, while waste elimination shows no significant impact in this context. These findings suggest that achieving the ambitious export targets set by Sri Lanka's apparel industry requires a strategic shift towards operational efficiency and quality enhancement. The study highlights the effectiveness of lean practices in improving operational outcomes, while also indicating that traditional strategies such as waste elimination may need re-evaluation. The implications of this research are critical for industry leaders aiming to navigate the challenges of global competition and economic pressures, as it suggests a strategic focus on continuous improvement, robust leadership, and integrated supplier involvement to drive efficiency and growth. These results not only contribute to the academic understanding of lean management but also offer practical insights for enhancing operational performance in a key sector of Sri Lanka's economy.
