DimensionInteraction-layer overlay onlyAI-native manufacturing architecture
System roleA Q&A or task entry point outside installed systemsData, applications, governance and AI form one manufacturing capability
Context sourceDocuments, screens and APIs assembled for each taskShared industrial objects, states, events and data contracts
IntegrationEach agent connects tools and interprets fields separatelyApplications and models reuse the same semantics and action interfaces
Business loopProduce an answer, report or one tool callConnect advice, approval, governed execution, outcome write-back and review
GovernanceRelies mainly on prompts and agent policyAccess, limits, approval, audit and rollback stay independent of the model
EvolutionModels, prompts and workflows tend to coupleModels change while enterprise objects, rules and decision records accumulate
This is not either-or. An operating plant can begin with a read-only sidecar and progressively add shared semantics, evidence and governed actions. A greenfield program can design the same contracts into the complete system from its first blueprint.
