Australian Government Architecture Reference Models Version 3.0
Published in March 2006 by the Australian Government Information
Management Office (AGIMO), the 2006 e-Government Strategy documents a
strategy to ‘deliver a more co-ordinated and citizen-driven focus to the
government’s e-government initiatives’ (http://www.finance.gov.au/egovernment/index.html).
A standard format for exchanging business data. The North American standard
for EDI is called ANSI X12. (TechTarget.com)
Computer-to-computer exchange of structured information, by agreed message
standards, from one computer application to another by electronic means and
with a minimum of human intervention. EDI is still the data format used by the
vast majority of electronic commerce transactions in the world.
The explicit description and documentation of the current and desired
relationships among business and management processes and information
technology. An EA describes the ‘current architecture’ and ‘target architecture’
to include the rules and standards and systems life cycle information to
optimise and maintain the environment which the agency wishes to create and
maintain by managing its ICT portfolio. The EA must also provide a strategy
that will enable the agency to support its current state and also act as the
roadmap for transition to its target environment. These transition processes will
include an agency's capital planning and investment control processes, agency
EA planning processes and agency systems life cycle methodologies.
Defines and describes the business aspects of the EA in terms of the current
and target business environments. The business aspects include the people
(internal and external resources directly involved in or impacting on the
business), the organisational structure (formal and informal structures and
social networks), the financial factors (budget funding, debts, investments), and
process (management, operational, support, business solutions,
metaprocesses). EBA includes business strategies for transition from the
current business environment to the target business environment.
