Conventional building design usually involves a series of hand-offs from owner to architect, from builder to occupant. This path does not invite all affected parties into the planning process, and therefore does not take into account their needs, areas of expertise or insights. In some cases, using the conventional method, incompatible elements of the design are not discovered until late in the process when it is expensive to make changes.
In contrast, the integrated design process requires multidisciplinary collaboration, including key stakeholders and design professionals, from conception to completion. Decision-making protocols and complementary design principles must be established early in the process in order to satisfy the goals of multiple stakeholders while achieving the overall project objectives.
