Drastic increases in the scale and complexity of engineered systems present many new challenges for the product development (PD) and engineering design communities. PD is characterized by the development of large, multidisciplinary, and networked systems that cannot be embraced by a single group or organization. Appropriate PD management principles can circumvent many of the difficulties that arise during the PD process. In this article, the author presents an integrative literature review that includes theories, models, and tools that can be used to manage complex PD. The review is structured around three PD analysis domains: product, people, and process. The review does not identify all the publications in any one PD domain, but instead addresses critical issues that exist within each domain and at the intersection of these domains. By reviewing these representative papers and creating a critical discussion around them, the intent is to provide an overview of the available theories, models, and tools for PD practitioners, while simultaneously identifying opportunities for future research.
