The production process in the manufacturing industries has proven wasteful of the resources in the production process over time. integrating lean principles in manufacturing activities has brought notable success in a complex and slow production process in an industry. This study aims at integrating lean principles into a product development process to eliminate breakdown cases as it makes the process easy as well as speeding up the product development in the automotive industry. Three major phases are applied in product development namely; the early concept phase, middle core design, and the launch phase. An exceptional definition of products development of lean principles is applied to come up with an analysis framework. Through interviews, observations, documentation, and experience barriers that cause a large number of wastes can be established. Lean principles will then be applied to eliminate such causes in the product development and then derive the conclusion that shows the industry the process of lean in product development in the entire process
