3Winchester Mystery House
- House without an architect
- Located in San Jose, California
- Built by Sarah Winchester between 1884 and 1922
- 160 rooms, 40 bedrooms, 10,000 windows
- Rooms around rooms
- 65 doors to blank walls
- 24 skylights in floors
- 13 staircases go nowhere
4What is Enterprise Architecture?
- Enterprise Architecture can be thought of as a
whole of government blueprint and roadmap to
guide how information systems and technologies
are able to support the achievement of the
Governments Outcomes.

Enterprise Architecture Research Agenda, 2006
- Enterprise architecture is the process of
describing, and the description of, the desired
future state of an organizations business
process, technology and information to best
support the organizations business strategy. - Blueprint
- The definition of the steps required, and the
standards and guidelines to get from the current
state to the desired future state. - Roadmap
6Why Enterprise Architecture?
- investing in IT without defining these
investments in the context of an architecture
often results in systems that are duplicative,
not well integrated, and unnecessarily costly to
maintain and interface. -
- US General Accounting Office
- Information Technology A Framework for
Assessing and Improving Enterprise Architecture
Management, (Version 1.1), April 2003.
7The US Experience
- Clinger-Cohen Act 1996.
- Requires among other things that the CIOs for
major departments and agencies should develop,
maintain, and facilitate the implementation of
architectures as a means of integrating business
processes and agency goals with IT. - E-Government Act of 2002
- Established the OMB Office of Electronic
Government - The offices responsibilities include overseeing
the development of EAs within and across federal
agencies.
8South Korea
- The eGovernment Act of 2001 prohibits development
of the same kind of software as developed in
other government agencies for processing the same
government business process. - 234 city/district governments were found to have
21 common business processes in respect of
residents, vehicles, land, buildings,
environment, construction, health, welfare,
livestock, fisheries, water supply and sewage.
These processes have been standardized and
redesigned since 1997. - 23 existing finance related systems that were
operating independently in various government
departments have been interconnected and
integrated into the National Finance Information
System (NAFIS)

Analysis
22Washington DC Before
- 21,000 employees (excluding public school system)
- 5.4 billion budget
- Services provided through 74 operating agencies
- 10 centralized e.g. purchasing, HR, IT, legal
services - 64 customer facing e.g. law enforcement,
transportation - January 1999 DC was half a billion dollars in
debt - Public services ranked at bottom of big city
ratings
23Operating Tenets
- Single point of entry
- All citizen requests to be routed to a central
point of entry - Guaranteed closure
- Citizen requests once submitted will be
fulfilled, no matter which agency or how many
agencies are involved - Benign service delivery
- Make it easy for citizens to deal with the
government
24Operating model
- Standardization of common processes
- End to end integration of processes
- Data sharing
- Nine service modernization programs launched in
2001 - Nine functional clusters administrative,
customer, educational, enforcement, financial,
human, motorist, property, transportation
services - Consolidation of servers, storage and software
25Washington DC After
- DC government improved from worst to first
- Government Technology magazine named DC portal as
the number one Web portal in government - Cost of modernization program 71 million
- Measurable cost savings 150 million

27The Importance of Standards Baltimore Fire 1904
- Major fire in downtown Baltimore
- More than 1,200 firefighters, 57 engines and 9
trucks arrive from 5 states and the District of
Columbia - Fire crews unable to assist, because
out-of-town hose couplings would not fit
Baltimore fire hydrants - Within 30 hours
- 70 city blocks devastated
- 1,526 buildings destroyed

29Examples of Standards
- Two letter country codes eg. VN for Vietnam
defined by ISO 3166-1 - ISO 8601 defines numeric representation of dates
in the form YYYY-MM-DD - TCP/IP standard developed and endorsed by the
Internet Engineering Task Force (IETF) through
RFC 2246. Part of the protocol relates to IP
addresses in the form nnn.nnn.nnn.nnn where nnn
is a number between 0 and 255 - W3C standards include HTML, XML, XSLT, XML
Schema, RDF, Web services, XQuery and XPath

36Conclusion
- Focus on defining the right EA process, and spend
less time debating and choosing an EA framework. - Start the EA effort by devising a future-state
architecture. - The secret of defining a great enterprise
architecture is knowing when to stop. - Large organizations are simply too complex to be
designed by a small group of enterprise
architects, no matter how smart they are.
