💡 Beyond Benchmarks: A Practical Framework for Measuring Success for Enterprise-Scale LLM Solutions 🗓️ Thursday 27th November ⏰ 12:30 PM GMT 🗣️ Li Fu, Data & AI Scientist

Most organisations today can build a prototype with an LLM — but far fewer know how to measure whether it’s actually working. In enterprise settings, where reliability, safety, and business value matter as much as creativity, having the right evaluation framework is the difference between a successful GenAI rollout and an expensive experiment.

This session introduces a comprehensive performance and utility suite designed specifically for evaluating generative AI systems like Retrieval-Augmented Generation (RAG) pipelines and agentic workflows. We’ll walk through a four-dimension framework that goes beyond model accuracy:

RAG Metrics: Precision, recall, grounding, and relevance of retrieved information.

Summarisation Metrics: Faithfulness, coherence, and compression quality of generated summaries.

Prompt Metrics: Effectiveness, robustness, and generalisability of LLM instruction design.

Ethics Metrics: Fairness, safety, factual integrity, and risk-based compliance checks.

Attendees will also learn how to connect these technical metrics to real-world outcomes, including user trust, operational efficiency, regulatory readiness, and ROI. Drawing on lessons from deploying GenAI in highly regulated enterprise environments, we’ll explore how to build automated evaluation pipelines, integrate human-in-the-loop feedback, and continuously improve performance post-deployment. We'll also talk about how enterprises balance technical metrics with business KPIs when deciding if a GenAI system is production-ready.

By the end, you’ll walk away with an actionable evaluation playbook that transforms GenAI from a promising prototype into a measurable, trustworthy, and business-critical system.
