The goal of Project M (for Modeling) is to synthesize complementary modeling and design methods for information-intensive services and applications – especially document engineering and user-centered design. In particular, we hope to develop more integrated or horizontal approaches to designing interfaces (front ends or stages) and the information systems and services that enable them or give them something to do (the back ends or stages). The merged methodology will span from end-to-end of service systems and be robust enough to accommodate person-to-person, self-service, and computer-to-computer contexts.
