Most AI systems fail not because the models are weak but because the coordination layer is missing. This talk will explain why multi agent systems need an orchestration director that manages planning, validation, governance, and execution across agents. I will walk through real architectural patterns for deterministic workflows, agent communication, escalation handling, and failure recovery. Attendees will learn how to design scalable and trustworthy AI systems that avoid chaos, hallucinations, and inconsistent decisions. This session is for engineers and leaders building production grade AI platforms beyond simple chatbot experiences.
