Overall design approach for urbanized information systems: Application of the method PRAXEME

Abstract

The IS urbanization is based on the metaphor of the city to meet the agility and responsiveness requirements of IS and to ensure the gradual evolution of the information system. The modeling approach BPM (Business Process Modeling) and SOA(Service Oriented Architecture are two key drivers for the design of an urbanized information system. However, they must be part of a comprehensive approach such as PRAXEME. In this article, we present the foundations of PRAXEME, and project its implementation on the hospital information system to improve quality of care, master costs by mastery of inter-application exchanges and use of services.
