Module 4 distills real-world failures from diverse industries to reveal the universal root causes of agentic system breakdowns: weak or missing runtime controls. You will study recurring anti-patterns such as unbounded execution, schema drift, timeout cascades, budget drift, phase drift, and missing evidence. The module concludes with AEI’s Runtime Readiness and Maturity Model, clarifying the cross-role responsibilities required to certify a system as production-ready.
