The Architecture-Centric Engineering team at the Carnegie Mellon Software Engineering Institute (SEI) has been extending its research from software architectures into the realms of software reliant system architectures, and system-of-systems and enterprise architectures. This work has focused on extending the principles of the SEI Quality Attribute Workshop and the SEI Architecture Tradeoff Analysis Method (ATAM) to develop methods applicable to larger scale architectures. We believe that enterprise architecture is critical to achieving business goals and that architectures are shaped by quality attribute requirements. So in this presentation we consider the following questions: How do we efficiently translate business goals into quality attribute requirements? How do we ensure that these quality attribute requirements are reflected in the tradeoffs and decisions that shaped the EA? We will begin by reviewing the SEI perspective on architecture-centric engineering. Next, we discuss how that approach scales from its original software context through systems and systems of systems. Lastly, we review the SEI methods applicable to systems and systems of systems, and finally propose how those methods can be extended to apply to enterprise architectures.
