Ticket Categories That Earn Their Keep
How to prune category trees so trend studies stay readable instead of collapsing into a fog of one-off labels.
Category trees grow the way vines do—quietly, then all at once. Every exception gets a new leaf, and six months later your trend study spends more time explaining the tree than reading the volume. The fix is not a grand redesign; it is a seasonal prune.
Keep categories that change decisions. If a label never shifts staffing, never informs a product bug bucket, and never appears in a leadership pack, merge it upward. Support boards in Vietnam often carry bilingual labels; decide which language is canonical for reporting and treat the other as display-only.
Test a category by asking what you would do if it doubled. If the answer is 'nothing specific,' the category is decorative. Decorative labels still help agents triage, but they should roll into a parent for charts.
When Maplecore runs a Ticket Trend Study, we freeze the taxonomy for the lookback window. Changing labels mid-study invents fake declines and fake growth. Freeze first, analyze second, then propose merges for the next quarter.
