Domain knowledge explains what matters in a workflow beyond its visible steps. It includes terminology, exceptions, quality standards and the reasoning experienced people use to distinguish a useful result from a merely plausible one.
AI automation becomes more dependable when this knowledge is mapped before implementation. Instructions, examples, references and tests can capture parts of it, while accountable experts remain necessary for ambiguity and changing real-world conditions.

Domain knowledge is specialized understanding of how a particular field or business activity really works. It includes its terminology, rules, exceptions, quality standards, and the judgment experienced people use when the written process is incomplete.
For example, an AI system drafting a legal document needs more than a template: it must understand the relevant jurisdiction, purpose, risks, and review standards. Instructions and examples can capture some knowledge, while experts remain necessary for ambiguity and change.
