LLM evaluation must be driven by real-world failures, not pre-written rubrics

Building effective evaluations for retrieval-augmented generation (RAG) systems requires a failure-driven approach rather than pre-defined rubrics. The process involves collecting and grouping actual failures observed during system operation, assigning domain experts to define standards, and then creating test cases based on these identified issues. This method ensures that evaluations are grounded in real-world performance and provide actionable insights for improvement, as traditional static testing is insufficient for dynamic LLM applications. AI

IMPACT This approach to LLM evaluation emphasizes real-world failures, offering a more practical method for improving RAG systems.
