The article deals with the formation of rational enterprise architecture. The description of existing approaches to the creation of EA structures, which, in turn, are aimed at the development of models and appropriate solutions for implementation, but have no strict formal metric representation, is presented. The complex of metrics to describe and measure enterprise architecture is offered. With the help of set theory, enterprise architecture is represented as a tuple of 8 elements, which includes sets of requirements, business processes, business systems, data elements, applications, technologies, constraints and business rules, as well as a set of indicators and their values. The set of main components of enterprise architecture is defined and indicators of their measurement are set. The introduced formal bases allow us to compare different variants of enterprise architecture as well as to make a rational choice according to certain criteria. In perspective, it is necessary to develop a set of invariant indicators being in several architectural representations, to be used in the analysis of compromise solutions for EA measurement.
Key words: Enterprise Architecture, EA, enterprise information architecture, metrics, measurement, design, representation, business processes, business systems, architectural views.
