Product Analytics

Goal

Build a measurement system that tells the team whether the product is working and whether the delivery engine behind it is healthy. It spans two layers: product analytics (a clean event taxonomy, funnels, retention, and statistically sound A/B experiments) and delivery metrics (the DORA Four Keys and the SPACE framework). The output is an analytics-and-delivery-metrics plan. The discipline throughout is rigor: a metric you cannot trust is worse than no metric, because it produces confident wrong decisions.
