Cleaning and Validation¶
Status: In Progress
What this page covers¶
This page explains cleaning decisions, transformation logic, validation checks, exception handling, and controls used to preserve auditability.
Cleaning Approach¶
- Non-destructive workflow preserving raw source data
- Standardization rules (types, labels, date formats)
- Deterministic transformations for reproducibility
Validation Framework¶
- Rule execution sequence
- Severity levels for issues
- Pass/fail outcomes and remediation tracking
Alignment with Provided Validation Rules¶
All validation checks were derived from the READ_ME_FIRST sheet included in the assessment file.
No metrics or insights were calculated until the validation framework was fully executed.
Checklist¶
- [ ] Add final cleaning rule matrix
- [ ] Add before/after examples for each major fix
- [ ] Confirm unresolved issues with business impact notes
