Enterprise Architecture Maturity Survey

The practice of Enterprise Architecture (EA)—the effort to align an enterprise’s operations, including business functions, processes, and information systems, with its business goals and strategic direction—is at a critical turning point. It has been 23 years since John Zachman published his seminal article on the topic,1 considered by many the birth of modern EA. Within the federal government, 14 years have passed since the Clinger- Cohen Act directed the development and maintenance of a federal EA to maximize the benefits of information technology (IT) within the government. But where are we today? How has EA evolved in light of fundamental changes in business and IT practices? Some level of maturation and growth in the past two decades is undeniable—including new frameworks and methods, the establishment of a chief architect position in many organizations, the adoption of EA within governance frameworks, and a competitive tools market. Even scholars and major business publishers have taken notice, as evidenced by such popular book releases as Ross, Weill, and Robertson’s 2006 Enterprise Architecture as Strategy: Creating a Foundation for Business Execution on Harvard Business School Press.

BIRT for Recovery How Open Source is Transforming Government Data into Dynamic Information Ecosystems

On February 17, 2009, President Obama signed
into law The American Recovery and
Reinvestment Act of 2009 (ARRA), pledging
a renewed focus on open government
and transparency, and making it clear that in order for efforts
to succeed this renewed focus had to become a top priority at
each step of its execution.
To provide initial guidance, the White House released detailed
documents on Recovery Act transparency and reporting,
which broadens the focus beyond funding programs to
include details pertaining to how performance information is
communicated to stakeholders, and the means by which this
may be accomplished.

Business Driven Architecture at the USDA Forest Service

The U.S. Forest Service (FS) was grappling with its inability to track, rationalize, and account for NEPA-related activities. Phase One conducted an Electronic Management for NEPA Modernization Plan that identified how IT could be used to improve NEPA compliance activities through the better use of knowledge management, collaboration, and business process improvement. By guiding the FS through a methodical Solution Definition process that included visual mock-ups, exhaustive field interviews, and recurring executive check-points, Phase One was able to identify stakeholder requirements and achieve widespread buy-in before the FS began building its solution.
