Welcome to GTRA

Many large government organizations struggle to realize the full potential of their IT investments. Consequently, management reforms have emphasized enterprise-wide, businessdriven approaches to architecting, investing in, and implementing IT solutions. Agencies have begun applying Enterprise Architecture (EA) and IT portfolio management as sound practices for ensuring that business needs and strategies drive IT investments. However, demonstrating measurable results from these activities continues to be a major challenge, and oversight bodies, such as the Office of Management and Budget (OMB), continue to raise the bar for what constitutes success.

Segment Architecture is an approach to developing detailed “deep dive” architecture for a distinct part of an enterprise in which measurable results can be achieved quickly. It encompasses the business-driven modeling and design of architectural layers (e.g., performance, business, data, applications and services, technology) at a more detailed and actionable level of granularity than traditional EA. Booz Allen’s Segment Architecture service offering extends the OMB-developed Federal Segment Architecture Methodology (FSAM) and helps establish clear relationships among strategic goals, business and information requirements, and measurable performance improvements.
