The overall aim and objective of readymade garments (RMG) is to improve the productivity and competitiveness of RMG industry in Bangladesh while simultaneously improving OHS and ergonomic conditions. In order to reach this objective the research strives towards gaining new knowledge about the dynamics among the major stakeholders in respect to co-development of sustainable OHS and productivity advancements. This research has identified the positive synergies between productivity and OHS conditions after analysing baseline data collected from fifty RMG industries. The Lean and OHS model for the sustainable productivity improvement are developed for the intervention process has been implemented in twelve RMG industries with positive outcomes as expected. The last phase of baseline data collection process is in progress to make a final comparison between intervening and on no-intervening industries in the journey of ensuring sustainable productivity. The research capacity in Bangladesh is strengthening by initiating and institutionalizing this novel research domain which eventually applicable to many countries.
