Adaptive enterprise architecture theory, sometimes abbreviated to AEA, involves adapting, defining, operating, managing and supporting (ADOMS) enterprise architecture design (Gill 2015). The focus of design is on the design of adaptive enterprise as an "adaptive enterprise service system" operating in the networked and connected ecosystem (system of systems).
Adaptive enterprise architecture theory, sometimes abbreviated to AEA, involves adapting, defining, operating, managing and supporting (ADOMS) enterprise architecture design (Gill 2015). The focus of design is on the design of adaptive enterprise as an "adaptive enterprise service system" operating in the networked and connected ecosystem (system of systems).
'''Focus:'''
Outer layer: The adapting capability involves context awareness, enterprise architecture assessment, rationalisation, realisation, and unrealisation of changes for adaptation. The adapting capability includes: scan and sense, interpret and analyse, decide and respond to internal and external changes (data-driven adaptability). The adapting capability in the outer layer initially identifies the change requirements (initiatives or ideas) that may initiate 1 or many projects. These project(s) initiatives or ideas can be further defined and handled through the inner layer via integrated engagement and governance. Deferred or low priority changes are pushed to unrealisation, which can be pulled again and reprioritized for realisation, if required. Inner layer: This includes defining, operating, managing and supporting the integrated adaptive enterprise architecture capability for handling the change for adaptation via identified projects from the outer layer.
The AEA theory focuses on the data-driven capability to "continuously '''scan and sense''' the internal and external environment for '''data''' about known and unknown events (complex event processing), changes or disruptions, '''interpret and analyse''' the collected data, and '''decide and respond''' based on intuition and rationale to expected and unexpected changes (threats and or opportunities) for adaptations".

The AEA theory includes the ADOMS approach, which is organized into two layers: outer layer and inner layer. The outer layer presents the adapting capability and the inner layer presents the defining, operating, managing, and supporting capabilities. The integrated inner and outer capabilities collectively define the “ADOMS” approach for the adaptive enterprise architecture. The outer layer identifies and feeds the adaptation changes (threat and opportunities) to inner layer. The inner layer handles the changes through the integrated engagement and governance.

==Application of theory==
The AEA theory can be applied to study and be embedded in the design of existing and new enterprise architecture frameworks. Following is an example of an AEA framework, which is organized into interaction, human, technology, facility, environment and security architecture viewpoints with overarching AEA theory elements (scan & sense, interpret & analyse, design & respond). Interaction centric viewpoint specifies the interactions between the human, technology, facility and environment elements. Human centric viewpoint specifies the business, information, social and professional architecture elements. Technology centric viewpoint specifies the application, data, platform and infrastructure elements. Facility centric viewpoint specifies the spatial, energy, HVAC (heating, ventilation and air conditioning) and ancillary elements. Environment centric viewpoints specifies the political, economic, social, technological, environmental and legal elements. Security is an overarching concern or viewpoint that considers AEA elements as assets and focuses on their resilience based on asset value and risk to such value.
