Describe a high-impact project via STAR

Using STAR, walk me through one project you led that measurably changed a core business metric. Include: Situation (company, product, date range), Task (specific target and non‑negotiable constraints, e.g., ≤6 analyst‑hours), Action (the 3 most consequential decisions you made, trade‑offs you accepted, stakeholders you aligned across regions, and one risk you intentionally took), and Result (before/after metrics with absolute numbers, percent change, and estimated $ impact, plus how you validated attribution). What would you do differently to 2x the impact with the same time budget, and what would you cut if forced to ship in 3 hours?
