The original data existed as a raw Excel export containing dates, products, quantities, prices, and store locations. While the data was technically complete, it wasn’t decision-ready.
Answering even basic questions, such as how revenue was trending, which products were driving performance, when customers were buying, or whether store locations behaved differently - required manual filtering, ad-hoc formulas, and repeated effort.
There was no single source of truth for key metrics, no consistent definitions, and no clear separation between high-level performance and detailed analysis. Insight lived in spreadsheets, not in decisions.
