Know it broke before your users do
Quality checks catch known problems; observability tells you when something's off that you didn't think to check. It's monitoring for your data, not just your servers.
The pillars to watch
- Freshness: is data arriving on schedule?
- Volume: did row counts suddenly jump or drop?
- Schema: did a column change shape unexpectedly?
- Lineage: what downstream breaks if this does?
From firefighting to early warning
With observability in place, you hear about a broken pipeline from an alert—not from an executive asking why the dashboard is blank.
