Facing the board with “LLM hallucinations” and need a clear, non-technical way to explain the risk? In this lesson, you’ll learn a concise, board-ready definition, map it to legal, brand, operational, and financial impacts, and present a simple prevent–detect–respond control framework with concrete governance asks. You’ll find crisp explanations, real-world examples, a reusable script and one-slide template, plus quick exercises to lock in the language and metrics. The result: confident, executive-grade communication that is precise, auditable, and action-oriented.
