Behind these three disconnects lies a disconnect between AI and enterprise architecture (EA). AI handles models, agents, and unstructured data and explores value through rapid trial and error. In contrast, EA aligns operations, systems, data, and authority to ensure stable operation of the enterprise as a whole. In other words, AI excels at “trying first,” while EA excels at “alignment and stable operation.”
If AI is overly adapted to the EA framework, its exploratory capability is lost; if it remains disconnected from EA, it will not be incorporated into core operations. Therefore, what is needed is not to directly connect AI to existing systems or completely overhaul core systems at once. Instead, it is to define data reference scope, execution authority, human approval points, and audit trails, and gradually incorporate AI into core operations without impairing the stability of EA. In this insight, this mechanism is referred to as the “interface” between AI and EA.
This discussion becomes even more urgent with the rise of AI agents. AI agents can autonomously make decisions within business processes and execute multiple steps. With conventional PoC-type AI, the practical impact of being disconnected from EA was limited. However, once AI agents begin operating across multiple systems and business processes, uncontrollable risks will arise unless the reference data, execution authority, human decision scope, and audit trails are designed.
For example, when a quality deviation occurs, an AI agent presents candidate causes by traversing inspection records, manufacturing conditions, material lots, change histories, and past quality issues along with corrective and preventive actions. At this point, it is necessary to design the scope within which data and authority from MES, product lifecycle management, enterprise resource planning, and quality systems are referenced. As technological options increase, it becomes more difficult to determine which technologies should be connected to which business events.
The problem is not a lack of technology. It is a lack of design to connect technology to operations, data, authority, and financial outcomes. At the core of designing this interface is a “value-connected ontology” that AI can reference.
An ontology is a structured body of knowledge in which concepts, relationships, and rules of operations are organized in a way that AI and systems can interpret, and it functions as a common language that enables AI agents to understand business context and make decisions. In this insight, an ontology connected to the structure of enterprise value is referred to as a “value-connected ontology.” Specifically, it is a blueprint that structures, in a form shared by AI and humans, how frontline events such as orders, inventory allocation, quality deviations, and delivery schedule changes propagate through business decisions to financial outcomes. Without a defined value-connected ontology, even if data exists, it will not be interpreted as business context, and AI will not function in the field.
In addition, to connect AI to core operations and financial outcomes, it is necessary to design not only the semantic structure but also which values to drive, which business events to capture, who makes decisions, and which EA to connect to, as an integrated whole. Therefore, this insight describes the value-connected ontology in terms of three layers and five design elements (Figure 2).
