What Raniben demonstrated

Built an end-to-end profit investigation that framed hypotheses, mapped KPI drivers, and audited the data before analysis. Solved the core SQL tasks with correct aggregation and margin logic, identified the weakest-margin region and largest category, and translated the findings into a board-ready narrative with prioritized actions on logistics, discount control, and raw-material hedging.

• Structural Hypothesis Framing
