Governance enterprise architecture (GEA): domain models for e-governance

Public administrations all over the world promote ambitious and costly e-government programmes. The required domain analysis is usually conducted on a local and ad hoc basis, due to a lack of commonly accepted domain models - in literature and practice - for the overall governance system. This paper summarizes a broad research modelling effort, which aims at developing a domain description for the overall governance system. We propose the Governance Enterprise Architecture (GEA) as a set of domain models that serve as a top-level enterprise architecture. To this point, the development includes five high-level generic process and objects models. Namely, we present the GEA mega-process model, the GEA interaction model, the GEA public policy formulation object model, the GEA service provision object model and the latest development of the GEA object model for the overall governance system.
