Enterprise Architecture and Systems Engineering

Factors such as the end of the cold war and increasing globalisation in terms of competition and social responsibility have significantly increased the complexity of events addressed both by governments and by industry. Furthermore, their responses are increasingly more constrained by economic and environmental issues. It is clear that the large complex “socio-techno-economic” systems (i.e. enterprises) that may comprise as well as create and deliver these responses must be both agile and efficient. An approach to the analysis, design and specification of such enterprises is presented which draws on state of the art Enterprise Architecture concepts and Systems Engineering techniques. The resulting EA/SE method enables clear justification of design, definition of interfaces and derivation of validated requirements. Comparisons are drawn to Zachman and ISO 15704 — GERA concepts.
