Principles & goals

Metrics must be clearly defined before measurement.Event-driven tracking forms the core model.Insights should be hypothesis-driven and action-oriented.

Use cases & scenarios

Compromises

  • Wrong conclusions from incomplete data.
  • Overoptimizing for short-term metrics instead of long-term value.
  • High implementation costs with poor architecture.
  • Version event schemas and document all events.
  • Work hypothesis-driven and prioritize by impact-effort.
  • Link quantitative with qualitative insights.

I/O & resources

  • Event stream from product clients
  • User and account context (anonymized or pseudonymized)
  • Product metrics and goal definitions
  • Dashboards and reports
  • Experiment results and action recommendations
  • Segmented insights for product teams

Description

Product analytics is the discipline of collecting, modeling, and interpreting user interaction data to inform product decisions and measure outcomes. It combines event tracking, funnel and cohort analysis, and experimentation to validate hypotheses. Applied across product discovery and iteration, it helps prioritize roadmap and optimize user value.

✔

  • Improves decisions through quantified user data.
  • Enables prioritization based on demonstrable user value.
  • Supports continuous optimization and experimentation.

✖

  • Requires reliable tracking and data quality.
  • Focuses mainly on quantitative view; qualitative insights often complement it.
  • Privacy and compliance requirements can constrain analysis.

  • Active users (DAU/MAU)

    Number of active users in a defined period; basis for engagement evaluation.

  • Conversion rate

    Share of users achieving a desired goal (e.g., purchase, signup).

  • Retention rate

    Proportion of users returning over multiple time points; indicator of long-term value.

PostHog (Open Source) deployment

Using PostHog as a self-hosted platform for event capture, funnel analysis and experimentation within a product team.

Amplitude for product metrics

Amplitude used for consumption analysis, cohorting and feature performance measurement in a SaaS product.

Experiment platform with analytics integration

Linking an experimentation platform with analytics to quickly validate hypotheses and measure business metrics.

1

Define KPI framework and metrics ownership.

2

Instrument core events and validation pipelines.

3

Build dashboards, funnels and initial experiments.

⚠️ Technical debt & bottlenecks

  • Inconsistent event naming conventions in tracking.
  • No backfill strategy for schema changes.
  • Monolithic pipelines without monitoring.
tracking-coveragedata-preparationquery-performance
  • Basing decisions solely on short-term engagement metrics.
  • Interpreting A/B tests without sufficient statistical power.
  • Event duplication causing skewed metrics.
  • Imprecise segment boundaries yield incorrect insights.
  • Confusing correlation with causation.
  • Ignoring data gaps and sampling effects.
