Microsoft IQ Deep Dive: Foundry IQ, Web IQ, Work IQ & Fabric IQ — a technical walkthrough of the context layer that lets enterprise agents reason over everything a business knows. This deck takes the four IQs one at a time and shows how they compose into a single retrieval brain for grounded, cited, and governed answers.
It starts with Foundry IQ, the retrieval brain: how agentic retrieval plans queries, searches across your sources, merges and ranks the results, and synthesizes one cited answer, along with the ingestion pipeline, hybrid search, reasoning effort, and three ways to wire a knowledge base into an agent. From there it covers Web IQ, an agent-native, structured, multimodal index of the open web delivered through MCP and blended directly into a Foundry knowledge base. Next is Work IQ, an intelligence and context layer over Microsoft 365 (and how it differs from Microsoft Graph), with its three protocols — A2A, MCP, and REST — a small set of generic tools built around a single guarded write path, and the option to ship an agent as an autonomous Agent 365. Finally, Fabric IQ brings it together as a shared business model over OneLake: zero-ETL shortcuts and mirroring, an ontology, a graph you query with GQL, semantic models, and the Fabric data agent.
Built for developers, architects, and decision-makers, the deck uses original diagrams, code snippets, and a short knowledge-check quiz, with links to runnable samples and session recordings. It's based on Microsoft's IQ Deep Dive series. Microsoft, Azure, Fabric, OneLake, Power BI, and other names are trademarks of their respective owners; this is an independent technical overview.
