A ProoV case study · educational project, not employment
Built a clear end-to-end profit-paradox analysis: framed the margin collapse with a hypothesis sheet and KPI driver map, audited the data for issues, and translated the findings into a concise executive narrative. The work connects the profit decline to raw-material inflation, logistics inefficiency, and discounting, then prioritises actions by impact and governance risk.
