Evals are considered the true crown jewel data asset for companies, as they provide context for why prompts were designed a certain way.

Offline evals involve running your app against a dataset before production to measure performance and track changes over time.

Online evals assess the app's performance in real-time using actual production data, allowing for immediate tracking of performance.

Building effective control evaluations is difficult, as they need to closely resemble actual deployment settings to yield valid insights.

There are three types of evaluations: offline evals, online evals, and in-the-loop evals, each serving different purposes in the evaluation lifecycle.

The evaluation process is continuous; it's not enough to just build a dataset and run it once. Ongoing evaluations are necessary to maintain quality in production systems.

Effective communication is crucial for product managers; it's a skill that needs continuous improvement throughout your career.

It's essential to periodically step back and evaluate whether your metrics are guiding you toward your product goals or just reinforcing past assumptions.

Metrics are essential in product development as they provide a numerical representation of the value we deliver to customers. It's important to measure not just internal metrics but also how well customers achieve their goals using our product.
