A Data Quality Service Level Agreement (SLA) is a formal contract that outlines an organization's expectations for managing and resolving data quality issues across systems. It specifies the data elements covered, business impacts of data flaws, and the quality dimensions that apply. The SLA includes agreed-upon quality expectations, acceptable thresholds, methods for measurement, and timelines for resolution. It also defines roles, responsibilities, escalation processes, and penalties for unmet service levels. Regular monitoring, inspection, and trend analysis ensure that data quality is maintained, helping to minimize business impact through timely remediation of issues.
