Government Enterprise Architecture

The Government Enterprise Architecture (GEA, formerly the GIA) provides the framework to support the development of better services for Queenslanders, more efficient and effective use of ICT in government, and effective partnering with the private sector.

The GEA provides a guiding framework for individual agencies, host agencies for multi-agency projects, and for whole-of-Government projects in the development, use, and management of ICT assets. The GEA is a federated architecture, one which acknowledges that the Queensland Government is a single enterprise, composed of autonomous agencies that are responsible for their own customers and business processes, yet are able to leverage and contribute to whole of-Government investments.

The GEA will also promote architecture practices in general to help drive business management improvements across the whole-of-Government.

The GEA replaces the Government Information Architecture.

The development of the GEA is an ongoing process. The initial formulation of the GEA consists of the overarching framework plus a series of domain classification models and a set of priority domain positions and targets.

Structure of the GEA

The Queensland Government Enterprise Architecture (GEA) Frameworks consists of three parts. These are:

the Meta Model i.e. a set of rules for structuring and populating the GEA;
the EA Classification Models i.e. a 4-layer structure for organising and navigating the business, information, application and technology elements of the GEA, and;
the EA Representations i.e. a collection of current and target enterprise architectures and, mechanisms/standards for achieving the target enterprise architecture.

The architecture resources within the EA representations section of the GEA are artefacts of various types including:

Domain profiles
Domain targets
White papers
Discussion papers
Strategies
Position papers
Standards
Guidelines
Domain specifications
