data quality assessment for reporting
How to Assess Data Quality Before Building Business Reports
Assess whether source data can support dependable reporting.
Inventory sources and owners
List systems, files, tables, exports, manual inputs, custodians, update cadence, access conditions, and retention. Identify the authoritative source for each entity and field. If ownership is unclear, corrections may not persist.
Profile the data
Measure missing required values, duplicates, invalid formats, unexpected categories, impossible dates, and identifier conflicts. Review representative records with process owners; automated profiling cannot determine whether a business event is correct.
Test consistency and timeliness
Compare definitions and values across sources. Determine when records become available, whether late changes occur, and whether the intended reporting period is stable. A timely feed can still be incomplete; a complete dataset can arrive too late.
Reconcile critical totals
Trace important counts and amounts to controlled source reports or records. Explain permissible differences such as timing, exclusions, reversals, and currency treatment. Do not silently force totals to match.
Decide readiness
Classify issues by impact and assign owners. Some reporting can begin with visible limitations; identity conflicts or unreliable critical fields may require correction first. Professional assessment may help with complex migrations, regulated data, or disputed sources.
Implementation limits and next decisions
The right approach depends on the organization's actual workflow, data, authority, vendor constraints, security and privacy obligations, change capacity, and tolerance for interruption. Document assumptions and unresolved questions before committing. Begin with a bounded decision or test where possible, define who owns operation after launch, and establish evidence for continuing, changing direction, or stopping. Where consequences are material, obtain appropriate technical, accessibility, security, legal, financial, records, or operational advice rather than treating general guidance as a substitute for assessment. Revisit the decision when requirements, vendors, risks, or operating conditions change.
