The Integrative Design Process (IDP) has the potential to radically change the way that decisions are made in building design and construction and improve project success and efficacy. However, integrative design projects often fail to realize success because optimal team structure is not achieved. How can we create and facilitate successful teams? In this paper, we analyze current integrative design process, offer a sharp, new understanding of team integration, and provide clear steps to optimize facilitation of project teams. We enhance existing knowledge on the integrative process by using social network science to define optimal team structure, why it is critical to success, and how to create it.
