"It seems better" is not shippable. Evaluation is the discipline that separates teams who improve their systems from teams who change them, and it is the skill hiring managers most consistently say is missing.
Covers benchmark contamination, LLM-as-judge and its biases, inter-rater agreement, and the statistics — from the inference module — needed to say whether a change is real.
A model-graded eval prefers verbose, confident, wrong answers. Find the bias, fix the rubric, and prove the fix.
