Lean principle application in an automotive product development process with special emphasis on peer reviews

Abstract

Global Automotive, a large US based, global manufacturer of automobiles, has made significant gains in manufacturing competitiveness, in part through application of a lean manufacturing approach to high volume assembly. A similar approach applied to product development can result in significant improvements in product design throughput, speed, cost, design quality, and innovation. With major product programs taking in excess of 36 months and a billion dollars to complete, the potential impact of process improvements is substantial. This thesis examines elements of Global Automotive Product Development Process. Some general guiding principles for Lean product development are also reviewed from the existing literature. Special attention is given to metrics for measuring product development performance at Global Automotive. The thesis focuses on the role of peer reviews in the development process. The analysis is performed using a work order data set for two automotive development programs. Score cards from Peer Review and a survey of the component engineering community are also used to assess the effectiveness and current state of the peer review process. The study found evidence that high scores on peer reviews do not guarantee that late changes will occur, if anything component groups with average lower scoring peer reviews generated led to consistent levels of late stage changes. The objective of peer reviews should clearly be to find as many problems as possible and participants should be encouraged to delivery "low scoring" reviews.
