Source-vs-warehouse gap analysis
Two systems disagree; nobody can prove where or why.
Problem
Two systems disagree; nobody can prove where or why.
Approach
Performed comprehensive gap analysis between an energy operator's source systems and their MDM/warehouse layer, then across unified metrics, production, and volumes reporting sub-systems. Every claimed discrepancy was backed by detailed analysis and reporting outputs - findings that survive scrutiny from both engineers and finance. The deliverables explained each gap, validated system behavior, identified remediation areas, and gave leadership a defensible basis for technical and business decisions. This is the diagnostic work that usually precedes every successful data platform engagement.

Proving a gap vs. claiming one
Anyone can say two systems disagree. The valuable work is proving exactly where, by how much, and why - with queries someone else can run. Each finding in this analysis shipped with its evidence: the reconciliation query, the affected records, and the root-cause classification. That standard turns gap analysis from finger-pointing into an engineering roadmap.
