DefinitionEnterprise Architecture: the explicit description and documentation of the current and desired relationships among business and management processes and information technology
OMB Circular A-130, revised 11/00

Enterprise ArchitectureDefines a framework in which one describes the current and future work activities and justifies the investments (personnel, data, applications) of an “enterprise”A precursor to electronic government (e-gov) and business process re-engineering

Reference ModelsBusiness Reference Model (BRM) –define mission-critical lines of business, business processes, and functionsTechnical Reference Model (TRM) –identifies and describes the information services used to achieve the BRMData Reference Model (DRM) – defines the data/information structures, definitions, and valids required by the BRM in the context of the TRM

Why an NSDI EA? Differences in understanding and implementing EA in various agencies Encourage communication between geospatial business professionals and IT/CIO offices within agencies Improve communication between agencies and departments on available services and data backed by a Business Reference Model Identify opportunities to fortify and share common geospatial services across all levels of government

Geospatial ServicesIncreasingly geospatial data can be accessed in real-time over local area networks and the Internet as if it were local dataMultiple organizations can benefit from the data being staged and maintained once and used many timesDesktop software and portals can use these services over the Web

NSDI EA Project ProposalDevelop an Enterprise Architecture for the NSDI to encourage the identification of geospatial data / service producers and consumers, and optimize resourcing for relevant programs within and across agency lines
![Page 13: Considering an Enterprise Architecture for the NSDI Doug Nebert FGDC Secretariat July 20, 2004.](https://reader036.fdocuments.in/reader036/viewer/2022082816/56649d875503460f94a6c023/html5/thumbnails/13.jpg)

OutcomesTraining / Familiarization of FGDC and GOS participants on FEA, EA Reference Model concepts, and the objectives of this projectDevelop use case scenarios that address critical provider and user processes and the data behind themDevelop formal Business, Data and Technology Reference models consistent with FEA guidelines
Developed cooperatively between NSDI members and industry via a consensus process
Validation of Reference Models via active prototyping and demonstrationA consensus process to evolve reference models via broad NSDI Stakeholder / Community involvement
![Page 14: Considering an Enterprise Architecture for the NSDI Doug Nebert FGDC Secretariat July 20, 2004.](https://reader036.fdocuments.in/reader036/viewer/2022082816/56649d875503460f94a6c023/html5/thumbnails/14.jpg)
18
Approach in Three PhasesPhase I*: Establish common understanding of objectives and terminology, develop key use cases for geospatial, establish EA Business Reference Model for NSDI that ties to agency-supplied FEA Lines of Business and equivalent BRM structuresPhase 2: Mature data and technical reference modelsPhase 3: Validate BRM, DRM, TRM via experimentation and prototyping
*This phase would be funded by the FGDC in FY04, with other phases potentially funded as FY05 budget allocations.
