In this concise instructional video, the speaker outlines a 15‑minute monthly supplier performance review that can be done continuously rather than at month‑end. The process consists of five steps: (1) continuously log each order received, noting arrival dates and inspection outcomes; (2) compute simple percentages for on‑time delivery (OTD) and inspection pass rate; (3) make a quick subjective rating of the supplier’s communication, pricing and flexibility compared to the prior month; (4) combine these metrics with a weighted formula to produce an overall score; and (5) compare the current month’s score to the previous month to spot upward, flat, or downward trends, with three‑month declines flagged as warnings. The speaker then recommends a quarterly deep‑dive where the accumulated data is reviewed to identify longer‑term patterns and decide which supplier conversations are needed.
