Signal prioritization when MMP taxonomy drifts
A rubric for deciding which events stay on the ladder when naming conventions rot.
Taxonomy drift is a cultural problem disguised as a tooling problem. When event names diverge, teams quietly invent shadow spreadsheets. We recommend a ladder review: fifteen minutes weekly, no slides, only the scoring sheet.
During review, downgrade signals that no longer have an owner responsible for freshness. Unowned signals should not influence prioritization even if they still fire in the MMP.
Upgrade signals only when a documented business question depends on them. If nobody can cite the question, the signal is decorative.
Finally, publish diffs. A one-line changelog entry beats a silent rename that breaks downstream creative naming. Your analytics partners will thank you when relay maps stop referencing ghost events.
