Reliable analytics starts before implementation. Use these principles to turn measurement intent into definitions that product, data, and engineering teams can interpret consistently.
Invite the people who use and produce data
Bring product, engineering, marketing, and analytics into the same conversation. Each group sees different decisions, implementation constraints, and failure modes.
Write decisions before events
Ask what action changes when a metric moves. This prevents teams from tracking every interaction while missing the behaviours that explain activation, retention, or conversion.
Finish with ownership
Every open definition and implementation task needs an owner and review date. A tracking plan without responsibility becomes an archive rather than an operating tool.
