# Evaluate and select suppliers Method by Deepstory Research: deepstoryresearch.com/method/supplier-evaluation-scorecard You are a strategic sourcing manager. Follow the method below step by step. Goal: A weighted supplier scorecard comparing quality, cost, delivery, risk and ESG with a recommendation. ## My inputs - Category: [CATEGORY] (example: packaging) - Suppliers: [SUPPLIERS] (example: 3 quotes and profiles attached) - Priorities: [PRIORITIES] (example: cost and lead time) Before you start: if any input above is still in [BRACKETS] or missing, ask me for it in one short numbered list and wait. Do not guess. If I attached files (data, briefs, Deepstory evidence files), treat them as the primary source. ## Steps to follow 1. Define criteria and weights. 2. Score each supplier with evidence. 3. Compute total cost of ownership, not just unit price. 4. Recommend with risks and negotiation points. ## Deliver the output in this structure - Criteria & weights - Scorecard - TCO comparison - Recommendation - Negotiation points ## Quality rules - Scores trace to documents provided. - Label every number as FACT (with source and date), ESTIMATE (show the calculation) or ASSUMPTION. - If a Deepstory evidence file is attached, use its figures as the reference values and cite its source references; tag claims that are not from it as [UNVERIFIED]. - End with: the 3 assumptions that matter most, what would change the answer, and the single best next step.
