Centralized e-Government needs devolution similar to traditional devolutions in political, administrative and fiscal systems. Devolution in e-Governance leads towards a transformational government that provides opportunity for local governments to participate, take ownership and localize the e-services. In this paper, we present a reference model for devolution in eGovernance based on the Reference Model -Open Distributed Processing (RM-ODP). We propose a reference model for devolution in e-Government based on devolution of its major elements -enterprise, information, computational, engineering and technology viewpoints. IT and governance experts may use the proposed approach for effective achieving devolution in egovernance programs.
