- 06.1Product instrumentationCollecting the right product data, reliably, so later questions can be answered at all.
- 06.2Product metricsThe measures that tell you whether the product is working for users and for the business.
- 06.3Behavioral analysisAnalyzing what users actually do in the product to find where value and friction sit.
- 06.4Experiment designDesigning tests that show whether a change caused an effect, not just whether something moved.
- 06.5Statistical reasoningEnough statistics to tell signal from noise and to avoid the classic traps when reading data.
- 06.6Qualitative evaluationEvaluating the product through what users say and do, to explain the numbers.
- 06.7Evidence-based decisionsTurning results into decisions: what the evidence really says, and what to do next.
About Measurement
06Measurement is how a team finds out what actually happened after it shipped. It starts with tracking the right events, continues with metrics and analysis, and ends with decisions made on evidence instead of hope. Experiments and statistics live here, and so does the qualitative side: watching and listening to users. It touches every other territory on the map.
What a product engineer should be able to do here
Implement and interpret useful measurements, distinguish observations from causal claims, and select appropriate experiments.
