Applications of Lean Manufacturing in Reducing Assembly Line Defects in Automotive Industry

Abstract - The automotive manufacturing sector continues to face persistent assembly line defects that increase operational costs, reduce product quality, and impact overall productivity. This study examines the application of Lean Manufacturing principles, including Value Stream Mapping (VSM), Kaizen, 5S, Poka-Yoke, Root Cause Analysis (RCA), Single Minute Exchange of Die (SMED), and Total Productive Maintenance (TPM), to systematically identify and eliminate the root causes of defects in autom
