The main purpose of this paper is to reduce the defects that will minimize the rework rate. We worked at 'Interstoff Apparels Limited', Bangladesh identifying sewing defects for a particular product (knit T-Shirts). Pareto analysis is performed to identify top defect positions from all the defects and seven are identified where 80% defects occur which should be the major concerning areas to minimize defects percentage. Cause-effect diagrams are constructed to show the root cause, effect, and 5S & PDCA is used to minimize the defects effectively. Recommendations have been added at the end of the study. http://pubs.sciepub.com/ajie/5/1/3/ajie-5-1-3.pdf defects Pareto Analysis cause-effect 5S PDCA quality productivity
