What is Enterprise Architecture Framework

This chapter presents the use of enterprise architecture to manage the growing complexity in aviation. Any aviation organization or air traffic management system can be considered as a complex enterprise which involves different stakeholders and uses various systems to execute its business needs. The complexity of such an enterprise makes it quite challenging to introduce any change since it might have an impact on various stakeholders as well as on different systems inside of the enterprise. That is why there is a need for a technique to manage the enterprise and to anticipate, plan, and support the transformation of the enterprise to execute its strategy. This technique can be provided by enterprise architecture, a relatively new discipline that focuses on describing the enterprise current and future states as well as providing a holistic view of it. The authors describe the modern enterprise architecture frameworks and provide an example of an application of one of them (European ATM Architecture framework) to identify and manage changes in aviation.
