| dc.description.abstract | The organizational effectiveness of textile, garment, and apparel manufacturing industries are measured through their production line efficiency and workers' performance. By its nature, these manufacturing industries are involved with a large workforce, complex operations, and several sequential production lines. As a result, different principles, methodology, and techniques have been implemented in parallel to the production process to enhance and integrate the uses of these resources. Specifically, in garment industries, sewing sections are considered as the most critical working zone because of large resource movements and significant chances of defects and reworks occurrences. As a result, this research is focused on the efficiency and performance analysis of sewing production lines of the case company. The case company describerd under this study has got a significant challenges on its sewing production operations. The figurative data analysed on this section indicated that several production wastes and defects on products are generated as it is lacking of consistency and poor workers performances. As a result, frequently, the line efficiency of this section is registered for lower and varying results in every production sessions compared to company’s targets. Therefore, the study under this paper has assured that the integrated applications of lean and six-sigma (LSS) methodology has been preferred to tackle-down these constraints of production efficiency and workers' performance level. Besides that, the joint uses of these methodologies are brought fundamental changes to the overall production process of the company and the integration can help to take-over the advantages of both. LSS is an approach that combines the philosophies, principles, and tools of both methodologies. Lean manufacturing operates through the principles of waste minimization and non-value adding activities by process optimization. Six-sigma is also known for minimization of process variation by the reduction of defects within the given standards. In conclusion, this study has got a considerable results on enhancing workers performance levels in each sewing operations for raising its line efficiency. Besides to that, a successful conceptional draft of the lean six sigma (LSS) model has been developed and validated for the satisfactory level of those production line efficiency and workers performance improvement. | en_US |
