Evals (evaluations) are the structured alternative: define what good looks like, rate a sample of outputs against explicit pass/fail criteria, identify failure modes, and trace them back through the pipeline to their root cause. Using a real-world AI audio news aggregator as a case study, the post walks through building a minimum viable eval process — starting with a spreadsheet and 30 samples — then scaling to an LLM-as-a-judge setup calibrated against human verdicts. Key lessons include using binary pass/fail criteria over numeric scales, targeting 80%+ agreement between human and automated judge, keeping humans in the loop for spot checks, and treating eval results as direct product roadmap inputs rather than background metrics. ## Full article daily.dev links to this article rather than hosting it.
