The results from case studies confirm the influence of procurement routes on the performance of
integrated teams. These results, on one hand, describe the socio-cognitive problems related to
integrated teams in transactional contractual arrangements of design-bid-build, and on the other
hand illustrate how an innovative procurement approach can help to resolve some of these
problems and improve team performance. The findings indicate, first that problems with
integrated design team efficiency are related to context and not process: they are not technical
but socio-cognitive, second that fragmented transactional contracting increases socio-cognitive
barriers that hinder integrated design team performance, third that new forms of relational
contracting may help to mitigate socio-cognitive barriers and improve integrated design team
performance.
