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.

  • Data contracts
  • Lineage
  • Freshness & completeness
  • Single definition
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

  1. 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
  2. 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
  3. 03The same metric, two numbersFinance and product report different revenue for the same day because each team defines the metric in its own query
  4. 04A backfill rewrote historyLast quarter's chart looks different than it did last week because a reprocessing job silently overwrote settled rows
  5. 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
