This evaluation, “Promoting Innovation: 2002 Assessment of the Partnership for Advancing Technology in Housing (2003),” found that while new technologies and production processes could help overcome serious problems for housing producers, “realizing these benefits on a broad scale is considerably hindered by characteristics of the housing industry that inhibit the development and diffusion of innovations.” The objective of this investigation was to make feasible recommendations for overcoming such barriers. The report is divided into four parts: . A literature review . An overview of the expert panels’ methodology . A summary of the expert panels’ discussions . Recommendations An extensive literature search and review was undertaken on the published literature related to risk, fragmentation, education/communication, and industry participant preference barriers to the adoption of innovation in the homebuilding industry. Altogether, nearly 40 documents were read and summarized. To develop a practical understanding of how these barriers affect technology adoption within the industry, three expert investigatory panels were convened in fall 2004—one on risk, a second on industry participant preferences, and a third on education/communication as
