||Conceptually, the development of an extensible infrastructure for Integrated Design and Delivery Solutions (IDDS) would appear to be a straight-forward matter. However, there are few current implementations in existence, and the majority of those that do exist are bespoke developments which support a restricted number of processes and analyses. This paper characterizes the wide range of technical challenges which are faced by those delivering on the promise of integrated design and delivery solutions. It examines the levels of IT support that can be offered for aspects such as: collaborative work processes; repositories of integrated data; management of information integration; and knowledge management processes. Alongside each of these challenges it identifies current approaches to supporting IDDS, both at a commercial level with tools that can be deployed today, and from the viewpoint of researchers working on future improvements to the IDDS ideal. The last part of this paper establishes a technology foresight for the technical development of IDDS. Providing a view of the technical future of IDDS over the coming decades with projections of the pathways that will lead to adoption of various forms of IDDS and the major obstacles where the dearth of solutions will delay the uptake of IDDS.
