Primary System
Engineering Index
Structured taxonomy of 12 modern engineering domains. Each domain is defined, classified by current state, and scored across five EDM dimensions. Traditional legacy engineering fields are excluded by design.
Critical New Concept
Domain Engineering is classified as a first-class engineering domain, not a metaphor. The transformation of business functions (Finance, Sales, Supply Chain) into formally engineered systems represents a structural shift in how enterprises model and govern operations.
