Smart mobile systems deployed in support of organizational decision-making objectives lead to a new, highly dynamic form of decision support systems (DSS) called network-DSS (NWDSS). We describe the salient properties of an NWDSS, emphasizing the central role of sensors and emergent knowledge processes (EKP) in such an environment. From a system design and development perspective, the defining property of sensor-driven EKP is that requirements cannot be identified in advance but rather emerge from the environment. This, in turn, demands an agile system development methodology which we argue must be built upon a flexible semantic system interoperability approach. We present the GINA (Global Information Network Architecture), a reflexive, executable, component-based, platform agnostic, model-driven architecture, which provides the necessary data, information and knowledge interoperability to enable services for smart mobile systems. We show how this approach works in a specific smart mobile system environment called Dragon Pulse.
