This talk discusses a research project on models for supporting of end-to-end eBusiness processes associated with design-centric applications. Design-centric applications are those where various business processes are initiated in the context of a design process. Our focus is on ad-hoc design environments that are characterized by collaborative processes among the initiators of the design and other players involved in moving the conceptual design to an actual implementation. This project is done in collaboration with the department of architecture, and the specific domain chosen for it is office design (either Business-to-Business or Business-to-Consumer). The conceptual results, however, apply to numerous other domains such as contract manufacturing, general construction projects, and designing and building one-of-a-kind complex products. The project examines next-generation eBusiness models and processes that best support collaborative office design, procurement of products and services, negotiations, and implementing (or building) the contacted solutions. A prototype system will be described and various implementation alternatives discussed.
