The effects of integrated Lean Six Sigma methodology with ergonomicsprinciples in the garment industry

The present paper introduces an integrated model that combines the use of ergonomics with Lean Six Sigma (LSS) methodology based on the DMAIC (Define, Measure, Analyse, Improve, and Control) approach. In each DMAIC phase, an additional ergonomic perspective was integrated to improve the process both from the efficiency and ergonomic side. The present study was carried out in a textile industry specialized in the manufacture of articles for technical use. The study’s aims are the following: achieving continuous improvement by eliminating waste, decreasing activities that are Non-Value Added, and preserving workers’ health while focusing on external and internal productivity. It began with a defined stage intended to increase Value Added (VA) activities by reducing Non Value Added (NVA) through waste removal, to around 48.5%, increasing the cycle time to 4.6 %. The finding has led to the conclusion that an integrative approach has ultimately secured the workers’ lives and boosted their operational performance.
