The Federal Enterprise Architecture (FEA) Practice Guidance describes important  concepts architects can use with stakeholders to deliver value to the business and  improve results in agency mission areas.  The guidance provides overviews of  architecture concepts, descriptions of the content included in architecture work products, and direction on developing and using architecture. 
The FEA Practice Guidance is not meant to be prescriptive, but to offer concepts to be applied using a variety of architectural frameworks and methodologies. The guidance does not cover enterprise architecture (EA) development and maintenance since there is already a broad body of knowledge on these topics There are four main sections of the FEA Practice Guidance:
- Section 1: Overview - Provides a high-level overview of EA concepts and principles.
- Section 2: Introducing Segment Architecture - Describes segment architecture concepts, the content included in segment architecture, and how to use segment architecture.
- Section 3: Developing Segment Architecture - Provides guidance on how to develop segment architecture, when one should be developed, and who should participate in its development.
- Section 4: Enterprise Architecture Transition Strategy - Describes what is included in an EA transition strategy and provides guidance on developing and using an EA transition strategy.
- Section 5: Measuring EA Program Value - Describes a continuous, customerfocused process relying on feedback from EA stakeholders and other value measures to increase the quality and effectiveness of EA products and services to support business decisions
