Measuring Products

by Karol Chojnowski

A practical playbook for designing product metrics, events, dashboards, and measurement systems around real user behaviour.

Think in measurement, not dashboards

Understand why product measurement should start with behaviour, evidence, and decisions rather than dashboards.

Map what matters

Define workflows, steps, entry points, exits, and completion so teams can identify what is worth measuring.

Turn behaviour into metrics

Learn how observed behaviour becomes events, metrics, dimensions, and meaningful signals for product decisions.

Design the measurement system

Connect workflows, events, and metrics into frameworks, metric trees, instrumentation requirements, and decision-led dashboards.

Operate the measurement system

Keep measurement useful, trusted, owned, and maintained as products, teams, and decisions change.

Toolkit

Use practical templates, examples, naming conventions, and checklists to apply the playbook in real product work.
