Data & Analytics
Nothing looks wrongLook again
In data & analytics, the dashboard that looks right is usually the one nobody has checked.By the time a chart looks wrong, the definitions have been drifting for weeks.
Trust the numbers
Green pipelines still lie
Bad numbers rarely announce themselves – the pipeline keeps running green while the meaning underneath it rots
The signs it won't survive contact with production
- 01Row counts drift day to dayA source that returned 4.2M rows now returns 3.9M and no job failed to flag the missing 300K
- 02Freshness lags without an alertThe last successful load was 30 hours ago but the dashboard still renders yesterday's timestamp as if it were live
- 03The same metric, two numbersFinance and product report different revenue for the same day because each team defines the metric in its own query
- 04A backfill rewrote historyLast quarter's chart looks different than it did last week because a reprocessing job silently overwrote settled rows
- 05Late-arriving events land in the wrong dayTimezone and event-time confusion pushes midnight activity into the next date and the daily totals stop reconciling
