Tracking every click creates volume, not clarity. Start with the questions the team needs to answer: where trials stall, which actions signal value, and how long meaningful progress takes.
Name events around completed user actions and attach only properties with a known analytical purpose. Document ownership, expected firing conditions, and test cases beside the taxonomy.
Validate the critical path before broadening coverage. A small, reliable set of events gives teams more confidence than a large catalogue with duplicate names, missing properties, and uncertain semantics.
