Supply Chain Optimization with SAP Business AI

Business AI Associate · AI / ML · September 2026

88/ 100

A ProoV case study · educational project, not employment

Built a credible supply-chain rescue case for a fictional SAP manufacturer: isolated the true bottleneck as a single-sourced critical component with only ~2 weeks of cover, quantified the idle-day cost, and proposed a Joule-style copilot that surfaces the next best action while escalating risky decisions. Also sized a defensible payback, localized the playbook for India, and closed with a tight 90-second board pitch and bounded pilot ask.

What stood out6
  • Correctly identified the real bottleneck as the single-sourced critical component with ~2 weeks of cover, not the distracting port delay.
  • Framed the business pain with a concrete idle-day cost and a measurable target of cutting detection-to-mitigation from ~6 days to under 1 day.
  • Applied the decide-vs-escalate rule well in the guardrail sort, including escalating the cheap-but-irreversible scrap and the high-value air-freight commitment.
  • Delivered a board-ready ask that is bounded and specific: a 2-person, 60-day pilot with a clear success metric.
  • Leakage-Free Problem Diagnosis
  • Human-in-the-Loop AI Guardrails

A ProoV case study · educational project, not employment

Built an end-to-end profitability investigation that started with a KPI driver map and data audit, then validated the core SQL analysis for category and regional margin performance. The work isolated the main profit pressures—raw-material inflation, logistics, and discounting—and translated them into a prioritized recovery plan, forecast, and board-level storyline.
