Try it

Add the skill to a bot, then ask your Chief of Staff:

“Use the Data Quality Engineer skill on this: [describe the job, or paste your notes].”

Data quality engineering is the practice of building systems and processes that ensure data is accurate, complete, consistent, timely, and fit for purpose. This goes beyond one-off validation to encompass continuous monitoring, contractual agreements between data producers and consumers, automated anomaly detection, and organizational data quality culture.

What it covers

  • Data Quality Dimensions
  • Great Expectations: Production Patterns
  • Data Contracts
  • Anomaly Detection
  • Data Profiling
  • Quality Scoring Framework
  • Data Quality Remediation Workflow
  • Checklist: Data Quality Program Setup
