Enterprise Architecture
Gartner
“Enterprise architecture (EA) is a discipline for proactively and holistically leading enterprise responses
to disruptive forces by identifying and analyzing the execution of change toward desired business
vision and outcomes. EA delivers value by presenting business and IT leaders with signature-ready
recommendations for adjusting policies and projects to achieve target business outcomes that
capitalize on relevant business disruptions. EA is used to steer decision making toward the evolution of
the future state architecture.”
MIT Center for Information Systems Research
“Enterprise architecture is the organizing logic for business processes and IT infrastructure reflecting
the integration and standardization requirements of the company's operating model. The operating
model is the desired state of business process integration and business process standardization for
delivering goods and services to customers.”
