Making Your Data Ready for Agentic AI

Pramod Sadalage and Prem Chandrasekaran — 2026-08-27

For thirty years we built data systems for human analysts, who supply the context, judgment, and skepticism to work around data that's incomplete or wrong. Autonomous agents supply none of that. They act on whatever they're handed, confidently. For data to be AI-ready we need to build a series of layers: a data foundation that makes data trusted, a context layer to apply proper meaning, and an acc
