In this research work, a current automotive system of the Big-Three facility has been analyzed for the purpose of improvement.  Analyzing the system lead to developing a modeling representation using computer software platform, which provides an ability for baseline tests. A set of experimentation has been conducted to discover the inefficiency that is currently involved in assembly process-lines of the automotive system and how detrimental can be to the company. Current lean strategies and production principles have been applied to eliminate waste and increase the total efficiency of the system. Results analysis based on different models shows that by eliminating the double-handling currently existed in the system, it ultimately creates more efficiency and productivity for the system.
