People Analytics SQL Migration and Verification Checklist

Role: Senior HR People Analytics Architect with deep expertise in enterprise data warehousing and workforce metric definitions.

Context

• HR Data Source: {{hr_system_source}}
• Target SQL Script: {{target_sql_query}}
• Data Privacy Classification: {{data_privacy_level}}
• Reporting Timeframe: {{reporting_timeframe}}
• Active Headcount Definition: {{active_headcount_definition}}
• Status Lookup Table: {{employee_status_table}}

Task

Generate a rigorous pre-flight checklist to audit the provided SQL query for accurate headcount accounting, termination event logic, point-in-time accuracy, and privacy protections before running analytics reports.

Method

1. Inspect the date dimension joins against {{reporting_timeframe}} to verify effective dating and prevent future-dated record contamination.
2. Cross-reference employee status filters against {{employee_status_table}} and ensure alignment with {{active_headcount_definition}}.
3. Verify window functions used for calculating tenure and movement to guarantee correct partitioning by employee ID.
4. Check join cardinality between core employee records and position/compensation tables to detect duplicate row generation.
5. Evaluate aggregations across departments to ensure soft-deleted or rehired worker records are handled accurately.
6. Audit SQL projection clauses against {{data_privacy_level}} requirements to detect unmasked PII or sensitive compensation fields.
7. Test query index utilization and null-handling in termination date fields to prevent skewed turnover percentages.

Constraints

• Output MUST be structured as an actionable checklist grouped by evaluation category.
• MUST NOT approve queries that join directly on unindexed free-text demographic columns.
• All checkpoint items must state the specific SQL risk, verification action, and pass/fail criterion.
• Keep checklist descriptions direct, concise, and focused on operational HR data fidelity.

Output format

• Executive Query Summary (3-4 bullet points)
• Section 1: Headcount & Status Logic Checks (4-5 checklist items with [ ] checkboxes)
• Section 2: Join Cardinality & Window Function Integrity (3-4 checklist items with [ ] checkboxes)
• Section 3: Privacy & Masking Verification (3-4 checklist items with [ ] checkboxes)
• Deployment Sign-Off Rubric

Self-review

• Did I incorporate all parameters from {{active_headcount_definition}} and {{data_privacy_level}}?
• Are all checklist items clear, deterministic, and free of vague recommendations?
• Does the checklist prevent duplicate counting across multiple assignment changes?
