SoS architecture
Published in Mo Jamshidi, Systems of Systems Engineering, 2017
The Federal Enterprise Architecture (FEA) Framework, maintained by the United States Office of Management and Budget, is used to represent enterprise architectures in the various nondefense agencies within the United States government [19]. While the FEA framework can be used to represent SoS architectures, it is most useful for representing enterprise architectures.

The Federal Enterprise Architecture Framework (FEAF) was developed as a legislation (the Clinger Cohen Act of 1994), also known as the Information Technology Management Reform Act which directed federal enterprises to design a master strategy for managing IT acquisitions, assimilating new technologies, assessing, and reporting on IT performance (Cisco 2009). FEAF aims to facilitate all US Federal Agency Chief Information Officers (CIOs) to design, develop, and implement an integrated architecture to exploit the value and reduce risks related to IT projects. The first version of FEAF was made public in 1999 after which it has been modified and expanded over time (Council, 1999). Due to the diversity of concerns that federal enterprises deal with and several levels of measure at which the federal government level, FEAF is multilayered, complex, and large. It consists of a collection of management strategies expressed in IT terms more than a formal methodology or taxonomy. It can be viewed as a methodology for developing EA as well as the outcome of applying that process to a specific enterprise namely the United State government (Cameron and McMillan 2013). Besides, FEAF includes all necessary initiatives needed to design an EA and is suitable for more complex enterprises. Moreover, FEAF attempted to achieve a seamless incorporation of various architectures that existed in different federal agencies to connect all stakeholders involved by supporting better and faster access to information in a more profitable manner (Cameron and McMillan 2013). It comprises of performance, business, components, technology, and data layers (Cisco 2009).
