Enterprise Architecture in Government
The European Interoperability Reference Architecture (EIRA), is an architecture content metamodel defining the most salient architectural building blocks (ABBs) needed to build interoperable e-Government systems. The EIRA provides a common terminology that can be used by people working for public administrations in various architecture and system development tasks. The EIRA was created and is being maintained in the context of the ISA Programme. The EIRA uses (and extends) the ArchiMate language as a modelling notation and uses service orientation as an architectural style. The EIRA is aligned with the European Interoperability Framework (EIF) and complies with the context given in the European Interoperability Strategy (EIS).
Being able to spot duplicative information technology projects in and among agencies was a key reason for the federal enterprise architecture initiative launched by the Office of Management and Budget in February 2002--but more than a decade later the Government Accountability Office says a limited review of agency IT projects turned up $321 million worth of spending on potentially duplicative projects over a 6 year period.
DO YOU THINK? OR DO YOU KNOW? PART II: The EA Value Chain, The Strategic Intent Domain, and Principles
NASCIO Enterprise Architecture Committee, September 2010: Investment in business intelligence and business analytics must be driven by enterprise strategic intent. Proper leverage of analytics should start with a clear understanding of the outcomes state government is trying to achieve. This issue brief presents the rationale for analytics using the NASCIO Enterprise Architecture Value Chain as a framework for organizing the thinking and the questions which eventually drive investment in analytics capabilities. It builds on the foundational concepts discussed in NASCIOs first issue brief on this subject, and strongly recommends an enterprise approach. Without an enterprise approach to analytics, investment across the enterprise is un-orchestrated and uncoordinated. That creates redundant investment in tools and training, and creates barriers to cross line of business collaboration. State government can not afford redundant and disconnected investment. One of the values of enterprise architecture is the management, optimization and simplification of investment within state government. Proper investment and application of analytics is essential to deploying effective and efficient government services. Finally, the level of complexity of analytical methods and tools depends on the complexity of the decisions and the issues.
The Common Approach to Federal Enterprise Architecture and FEAF-II was launched publicly on May 2, 2012 in an important memo from Federal CIO VanRoekel. The Common Approach is clearly inspired by the EA3 Cube, and replaces/upgrades FSAM..
FEA Reference Models include the Consolidated Reference Model Version 2.3 and Data Reference Model 2.0. FY10 FEA Reference Model Mapping Quick Guide.
Over the past two decades, the government sector has emerged as the area of largest implementation of enterprise architecture - a critical success factor for all types, scales, and intensities of e-government programs. Advances in Government Enterprise Architecture is a seminal publication in the emerging and evolving discipline of enterprise architecture (EA). Presenting current developments, issues, and trends in EA, this critical resource provides IT managers, government CIOs, researchers, educators, and professionals with insights into the impact of effective EA on IT governance, IT portfolio management, and IT outsourcing, creating a must-have holding for academic libraries and organizational information centers.
The Operating Units of the Department of Commerce (DoC) have made a heavy investment in the development of enterprise-wide IT Architectures. We need to ensure that the Department continues to build on previous efforts and fully realize the benefits of IT Architecture. Assessments of IT processes within an organization are needed to evaluate where we are and where we should be headed. The Department has developed an IT Architecture Capability Maturity Model (CMM) to aid in conducting such assessments. The goal is to enhance the overall odds for success of the IT Architecture by identifying weak areas and providing a defined path towards improvement. As an Architecture matures it should increase the benefits it offers the organization.
This FEAPMO-document describes a Federal-wide E-Gov target conceptual architecture, the Common Reference Model. The architecture is based on the business requirements derived from the initiatives as well as system engineering design best practices. It provides a workable description of the components needed by E-Gov Initiatives and business activities to move rapidly into the web service-enabled business transaction environment.
