The consultant works with Data Owners, Data Stewards, business experts, architects, engineers and system teams to ensure that quality expectations are tied to real business needs and authoritative reference sources.

• Calculate and validate quality results and explain the implications for operational and analytical use.
• Maintain data-quality issue registers and support transparent prioritisation based on impact, urgency, frequency, sensitivity and complexity.
• Facilitate root-cause analysis across process, people, system, integration and data-design factors.
• Develop remediation plans with owners, target dates, dependencies, validation steps and closure evidence.
• Coordinate quality controls with metadata, master data, architecture, engineering, security and analytics teams.
• Define dashboards and reporting routines for ongoing monitoring and escalation.
• Validate remediation outcomes and distinguish corrected records from resolved root causes.
• Train client teams to maintain rules, interpret measures, investigate issues and govern exceptions.
