To enable 'future state' service strategies new architectures are required to enable government and regulatory operations to be more open to disruption and innovation. Through a service science perspective, this paper outlines a government services architecture (GSA) to enable social welfare delivery to be driven by, and responsive to, changing social and economic forces. Using Service Dominant Logic as a kernel theory, we developed an initial set of requirements from which three models were derived: 1. GSA Theoretical Framework (research and theories); 2. GSA Meta-Model (objects and relationships) and; 3. GSA Functional Model (functions and interactions). The research provides a practical application of SD-Logic by responding to limitations of government service business models and supporting approaches to architecture. The implications for government and further research is identified.
