How to Build an E‑commerce Data Metric System
This article explains the concepts of good data metrics, how to identify and select appropriate indicators, and provides a step‑by‑step methodology—including the OSM model and a practical e‑commerce case study—for building a comprehensive data metric system that drives business growth.
Introduction – The speaker, a data analyst and product manager, outlines the agenda: understanding data metrics, how to construct a metric system, and a hands‑on e‑commerce case study.
Data Metric Cognition – Good metrics should be comparable, simple, ratio‑based, and actionable. Comparability requires a baseline; simplicity ensures adoption; ratios provide operational insight; and metrics must guide decisions.
How to Find the Right Metrics – Metrics are classified into qualitative vs. quantitative, vanity vs. actionable, exploratory vs. reporting, leading vs. lagging, and correlated vs. causal. The article explains each type with examples such as user acquisition, retention, and revenue.
OSM Model – The OSM framework (Objective, Strategy, Measure) guides metric system design. The objective (core or "North Star" metric) defines the ultimate business goal; strategy breaks the objective into sub‑goals; measures evaluate strategy effectiveness.
Practical E‑commerce Case: Diaper Pull‑New Strategy – Using a diaper product, the article demonstrates selecting a North Star metric (third‑purchase users), decomposing it into first‑purchase count, second‑purchase retention, and third‑purchase retention, and then defining strategies (e.g., free trial, coupons) and corresponding measurement indicators (exposure, click‑through, conversion rates).
Q&A – The speaker answers questions about defining churn users, ensuring metric completeness, distinguishing new vs. old users, and why third‑purchase count is preferred over GMV for a repeat‑purchase product.
Overall, the talk provides a systematic approach to designing, implementing, and iterating data metric systems that align teams, monitor performance, and drive data‑driven growth in e‑commerce contexts.
