Improving interorganizational data interchange for drug development

This paper presents a reengineered process that uses a markup language to d o interorganizational data interchange between the participants in the US d rug development process. The two major goals of this paper are to present ( 1) a detailed enough description of the reengineered version of this proces s that a practitioner will be able to use it and (2) a case-study of the re engineering of an interorganizational data interchange system that is appli cable to other areas in health care. The detailed description is augmented with a companion web-site that shows all programs in a working prototype. T he case-study uses an IDEF0 model to show the structure of benefits from ma rkup standards for interorganizational data interchange. (C) 1999 Elsevier Science Ltd. AII rights reserved.
