Episode #47 - Testing LLMs, Agents, and RAG Systems

Episode 47: Why Your AI Testing Strategy Is Probably Broken — And What to Do About ItWhat does it actually take to test an AI system that can confidently lie to you up to 30% of the time? In this episode of The AI Strategy Blueprint, host Lara Wilson dives deep into Chapter 16 of John Hanby's book — and this one is required listening for every executive who has signed off on an AI deployment without fully understanding what's being validated.The core problem is this: your IT team is trained to test deterministic software, where two plus two always equals four. AI doesn't work that way. LLMs are probabilistic engines — the same prompt can return a different answer tomorrow than it did today. Lara breaks down exactly why applying traditional QA frameworks to AI doesn't just fall short, it actively creates blind spots. From hallucinations in raw LLMs to cascading failures in autonomous agents, the risks are real, specific, and entirely testable — if you know what you're looking for.Autonomous agents are where the stakes get truly high. Lara walks through the difference between an AI that drafts a response for your review, and one that actually clicks send, updates your CRM, and adjusts your marketing budget. Task completion validation, guardrail testing, and the emergency kill switch — these aren't abstract concepts. They're the difference between a controlled deployment and a runaway agent ordering ten thousand units with next-day freight. Could your team stop that agent in time?Then there's RAG — Retrieval-Augmented Generation — which Lara calls the crown jewel for enterprise AI. But it comes with its own four-pillar validation framework: retrieval quality (did it find the right documents?), grounding verification (did it actually use them?), citation accuracy (is it showing its work honestly?), and conflicting information handling (what happens when your 2021 policy contradicts your 2023 memo?). Silent failure on any one of these pillars isn't a tech glitch — it's a compliance liability.The episode closes with the Human-in-the-Loop 70-30 model: a framework that treats human oversight not as a fallback, but as the optimal strategy. If AI can turn a 10-hour task into a 1-hour task, you've unlocked massive efficiency gains — and keeping a human in the loop for the final 20-30% is what gives your decisions defensibility in an audit or a courtroom. Tune in to learn how the crawl-walk-run approach, risk-based review gates, and smart exception handling design can make your AI deployment both powerful and bulletproof.
