Lesson 12 of 20
Make AI Cross-Reference Three Documents Before You Renew a Supplier
Supplier Screening & Evaluation · Raw Materials / Chemicals
Synthetic case data — evidence from real ChatGPT, Claude, Gemini and Copilot runs.
One file, three documents: annual-report excerpts, a news digest, and an ESG risk summary for a fictional supplier. Paste it into any AI tool to follow along.
Your chemicals contract expires in 60 days. You're the category manager for Aethon Chemical Industries — $4.2M a year, seven years running, no quality complaints — and your procurement director wants a financial health screen before he approves a three-year renewal. His only instruction: "Something about their CFO leaving doesn't sit right." Your job is to turn a hunch into a one-page assessment he can act on — by Thursday.
Three documents are on your desk: annual-report excerpts, a news digest, and an ESG risk summary. On the surface, every one clears the bar. And if you paste them into an AI tool with a one-line prompt — "is this supplier healthy?" — the AI catches individual red flags (falling cash flow, rising debt, governance turnover) and adds conditions to the renewal. In our four real runs (2026-07-02), none of the four tools rubber-stamped a three-year deal.
Useful. But incomplete. In those same four runs, none ran the quantified 24-month coverage test that shows ~$108M needs refinancing. None connected the governance collapse to the debt cliff to the bond price as a single sourced pattern. None produced the sourced, cross-document risk assessment a director can act on without translation. Those appeared — from the same tools, the same documents — only when the prompt told the AI to cross-reference.
This lesson teaches you how to write that prompt. And how to grade what comes back.
You’ve read the free three. The other seventeen are where the misses live.
The first lessons show what a general-purpose AI catches on a procurement task. The rest show what it misses — the unit conversion that survives an expert prompt, the two clauses it lists but never connects, the table that contradicts its own arithmetic. That gap is the job.
