This article presents an Instance-First approach to Architecture Intelligence in ServiceNow, connecting Enterprise Architecture decisions to evidence available in the platform. It introduces a Discover → Model → Validate → Visualize approach and distinguishes architectural relationships as EXISTS, INFERRED, or CSDM GAP. The paper covers evidence and provenance, CSDM alignment, Application Service to Business Service visibility, architecture drift, governance, implementation roadmap, and business value. It includes a reference architecture and demonstrates how ServiceNow operational evidence can support more trustworthy, explainable, and continuously validated architecture decisions. Evidence submitted: Final Architecture Intelligence Thought Leadership whitepaper with supporting reference architecture.
