Freshness: Pay attention to the most recent refresh instances for all knowledge tables, as knowledge pipeline failures might go unnoticed in additional granular areas. As an example, an integration concern pausing the gathering of company-size knowledge from Clearbit may persist with out instant detection.

Segments: Establish points inside particular segments, similar to mislabeling sure product classes, which will be difficult to detect with out correct checks in place.
