The objective of this literature review is to expand upon the research associated with relationship between the use of cost engineering approaches and six-sigma project success when designing or redesigning products in the manufacturing industry. The objectives of this literature review are two-fold. First, is to analyze contextual peer-reviewed literature pertaining to the impact of using cost engineering methods and practitioners in six-sigma projects focused on new or redesigned products. Second, to identify the causes and factors for six-sigma and related methodologies failures focused on product design and redesign. As a result of this literature review this research aims to provide a cursory look at discovering research gaps that could be addressed further.
