Project Integration Architecture: Inter-Application Propagation of Information

A principal goal of the Project Integration Architecture (PIA) is to facilitate t he meaningful inter -application transfer of application -value -added information. Such exchanging applications may be largely unrelated to each other except through their applicability to an overall project; however, the PIA effort recognizes as fundamental the need to make such applications cooperate despite wide disparities either in the fidelity of the analyses carried out, or even the disciplines of the analysis. This paper discusses the approach and techniques applied and anticipated by the PIA project in treating this need.
