Deep in the layers of organizational structure lie potential savings. EA is your
metal detector.

EA and Buried Treasure
Enterprise Architecture (EA) Definition• Enterprise Your business; whatever it is you’re doing. Can be an
organization (for instance, DOI or MMS) or it can be one line of business (fighting wildfires) that cuts across several organizations
• Architecture The structure or structural description of your business• Enterprise architecture (EA) The structural description of your business
– Can be in the form of models, diagrams, or text– Describes how the enterprise operates
• How business processes and rules relate• How information flows• Where work happens• Who the users are• What hardware, software, data, and security
is used for the business– First step is to evaluate the existing EA– Second step is to decide what EA the
business needs for the future• Modernization blueprint Plan for a
future EA

EA and Buried Treasure
… agency executives have historically not understood the purpose, content, and value of these architectures…
—GAO Report to Congressional Committees, February 2002
Executives need to understand EA, and make an informed decision whether to support or reject it

EA and Buried Treasure
Try it before you buy• EA is not “all or nothing”
– No need for sight unseen investment– Highest yields are from the longest-term investments– But there are also gold nuggets just lying around—”somebody else’s problem”
improvements that everyone agrees on, but nobody has fixed• EA makes recommendations. Managers weigh potential improvements
against funding, and decide how far to go
System X System X+ System X2O&M $ Investment $
What wehave now
We can make tacticalimprovements now
We can make strategicimprovements in our next
investment
Short-term effort:better system,some savings,
now
Long-term effort:much better system,
great savings,in the future

Further, skilled human capital in the discipline of enterprise architecture is a scarce resource.
—GAO Report to Congressional Committees, February 2002
To succeed, EA needs the support of executives who understand what it’s for.

EA and Buried Treasure
What drives EA• We are spending millions collecting data artifacts which we are not using effectively
– EA models and analysis help you understand the data and use it to make decisions– Money spent on data collection is wasted without the investment in EA– Like buying a top-of –the-line computer; it is wasted unless you also invest in a little
electricity to power it• OMB’s EA push means everyone in the government has the same goal to shoot for
– Easier to talk and share data with other organizations• Literally gives organizations the same vocabulary
• Stop IT investments growing like a fungus; get investments in line with our mission– “Whiz-bang” is not the right reason to invest– We need solid business analysis to base our IT choices
on – We need long-term cost-effectiveness
• EA will speed good business cases through and stop bad ones early on
• EA will help with other initiatives– Security– Asset management– Configuration management

DRAFT
EA and Buried Treasure
Why is EA different from past efforts?• Response to GAO report of “immature” federal EA
programs– OMB oversight increased– OMB is also looking deeper into programs
• Answer to personnel cuts from OMB workforce planning– Organizations have to do more with less
• Answer to “retirement bubble” in some areas
– Corporate memory is lost when many retire at the same time• Objective view of business
– EA team is outside the other organizations• Response to faster technology development
– Technology is also outdated faster– Technology decisions must be both quick and correct
• Driven by business, not flashy technology– To get the latest gadget, you have to show a business need

EA’s Payoff
Course Topic 2
Why EA is valuable.

DRAFT
EA’s Payoff
What’s valuable about EA?• To improve a complex organization, first you have to
understand it. • EA highlights what’s important
– Models the organization before and after the improvement – Shows inefficiencies and redundancies– Gives recommendations, risks, costs, and benefits– Shows where local efficiencies cause national inefficiencies
• Result of penny-wise, pound-foolish decisions• EA shows the overall most efficient solution
• Decision-makers can base decisions on facts, not anecdotes

DRAFT
EA’s Payoff
I think a lot more decisions are made on serendipity than people think. Things come across their radar screens and they jump at them.
—Jay W Lorsch, professor, Harvard Business School
EA prioritizes what comes across decision-makers’ radar screens, and gives them facts for decisions

EA’s Payoff
EA saves money by showing true costs• EA shows the big picture, total cost of
operations (TCO), not just the immediate price– Cost of maintenance– Cost of incompatibility– Cost of duplication– Cost of effort spent on non-mission tasks

EA’s Payoff
Results of EA • Data collection and reporting standardized across the Interior• Interior in line with OMB funding requirements• Interior in line with federal EA guidance• EA improves customer service
– Data compatibility allows more one-stop shops– Less customer confusion at finding similar businesses in different
organizations– Streamlined business helps customer ask the right office the right
question the first time• Long-term vision of EA: use related money to buy related items
– Example: Quit sending money to many agencies to do the same recreation job many different ways
– Use recreation money for the recreation line of business, with the same standards, whatever agency it shows up in (see http://www.recreation.gov)

A Tour of the Diggings; What’s Going On
Lines of business• Alternative way to look at Interior structure• Looks at the job instead of the organization• For instance: many bureaus manage
finances (everyone has to do paychecks!)– EA looks at all the financial management
programs– Finds the best program that will work for all
organizations– Standardizes all the programs– Saves money
• Bulk buys of technology• Technology, data, and training is interchangeable
between organizations• Better management of technology updates Many agencies,
one business: law enforcement

A Tour of the Diggings; What’s Going On
Phases of an EA effort:1. Envision the future architecture
• Sketch out what the organization will need2. Determine scope, collect data
• Interview system experts to find out how they do their job, and analyze the findings
3. Align Interior architecture with federal architecture• Compare what Interior is doing with the FEA
reference models4. Build modernization blueprints, at tactical and
strategic levels• Tactical blueprint is a road map to short-term savings
(for instance, on project management)• Strategic blueprint is a road map to long-term
savings (for instance, on investments and business cases)
Phase 2Mining for data

A Tour of the Diggings; What’s Going On
In academic science, interdisciplinary work is productive and praised, but is relatively rare. Scientists don’t need to cooperate to have their results fit together: they are all describing different parts of the same thing—nature—so in the long run, their results tend to come together into a single picture.
Engineering, however, is different. Because it is more creative (it actually creates complex things), it demands more attention to teamwork. If the finished parts are going to work together, they must be developed by groups that share a common picture of what each part must accomplish. Engineers in different disciplines are forced to communicate; the challenge of management and team-building is to make that communication happen.
—K. Eric Drexler, U.S. researcher, lecturer
EA gives different groups a common picture of the overall mission and how each piece of work fits into
it.

Bureau efforts • MMS, BLM, and USGS are well underway with EA work• Interior EA work will help standardize bureau efforts
– Complements, rather than replaces, bureau EA– Reduces total cost of EA: methods get paid for once at Interior level, then used
by all bureaus– Interior EA will follow federal guidance, bureau EAs will follow Interior– Interior EA will use best practices, lessons learned, and data from bureau EA
efforts– Scope of bureau work will be clearer

• Interior EA will be mapped to specific structure of each bureau
– That information gets mapped to the structure the Interior needs for managing resources
– Interior information gets mapped into what the OMB needs

… [EA should] be treated as a funding priority and [needs to] overcome the embedded cultural resistance to the non-parochial, entitywide approach that enterprise architectures promote.
—GAO Report to Congressional Committees, February 2002
EA helps agencies share data and technology with other agencies, and it helps the federal government understand and
approve of where its money goes.

EA in government and industry • DOD is a leader in EA; may be the only government agency more
complex than Interior– Complexity comes from different parts of an organization doing the same
business– http://www.defenselink.mil/comptroller/bmmp/pages/arch_home.html
• Several state governments have websites about their EA efforts– Kentucky EA http://enterpriseit.ky.gov/ – Virginia EA http://www.cots.state.va.us/EA/eaabout.htm
• Industry and universities are also involved– Stanford University EA http://www.stanford.edu/group/APS/arch/ – University of Iowa enterprise security architecture
