Winchester 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

What 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.

Gartner on Enterprise ArchitectureSource
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

6
Why 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.

The 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.

8
South 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)

Four Operating Models
High
Process integration
  • Diversification
  • Few data standards across business units
  • Most IT decisions made within business units
  • Makes sense if few if any shared clients, no
    overlapping transactions

Inception dates of various EA frameworks
  • Zachman Framework, 1987
  • The Open Group Architecture Framework (TOGAF),
    1995
  • Command, Control, Communications, Computing,
    Intelligence, Surveillance and Reconnaissance
    (C4ISR), 1996
  • Treasury information Systems Architecture
    Framework (TISAF), 1997
  • Federal Enterprise Architecture Framework (FEAF),
    1999
  • Treasury Enterprise Architecture Framework
    (TEAF), 2000
  • Department of Defense Architecture Framework
    (DODAF), 2003
  • A new framework has been adopted every 15
    months since the
  • Clinger-Cohen Act became law in August 1996

Washington 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

23
Operating 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

24
Operating 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

25
Washington 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

The 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

Examples 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

Conclusion
  • 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.
