Major feature launches, pricing changes, and seasonal campaigns can age a path baseline in weeks. Watch for rising “other” routes, support themes that never appear in your top paths, and stakeholders inventing unofficial journey labels.
A light refresh cadence—monthly for fast-shipping apps, quarterly for steadier products—keeps product, analytics, and support speaking the same language.
Refresh is not a full rebuild. Confirm which journeys still define severity, prune stale routes, and only invent new path rules when a new journey becomes critical.
