Document data provenance and representativeness gaps: Which evidence is most important first?
Provenance and representativeness evidence directly addresses the known regional and seasonal data-quality concerns.
The question
A retailer uses an EU AI Act high-risk demand-planning system, assuming the applicable duties apply. Training data combine stores with different seasonal patterns, and missing regional values are known. Which evidence is most important first?

- Compare forecast accuracy with the supplier’s published benchmark.Benchmark comparison informs performance but does not establish provenance, representativeness, or handling of known regional gaps.
- Limit records to the final cleaned dataset used in production.A final dataset alone omits lineage and decisions about seasonal variation, missing values, and suitability for intended use.
- Document data provenance and representativeness gaps. ✓Data-governance evidence should show where data came from and whether coverage and quality fit the system’s intended purpose.
- Obtain store managers’ general approval of the training dataset.Manager approval may support governance, but it does not document data origin, coverage, quality, or missing-value treatment.
The trap
Match evidence to the stated data defect; known gaps call for lineage, coverage, and treatment records. How to remember it
Provenance and representativeness evidence directly addresses the known regional and seasonal data-quality concerns.
