Supplier performance scorecard

Purpose

Measure supplier performance on a common basis and turn the result into evidence-backed review priorities. Preserve the difference between a calculated metric, a target, and a recommendation.

Scope

Purchase orders, promised and actual delivery, quantities, inspection or complaint records, prices, service cases, criteria, weights, and prior scorecards. Excluded: changing supplier ratings in a system, negotiating, or terminating a supplier.

Data basis

• Order, delivery, receipt, and quality tables.
• Price agreements, service cases, and response records.
• Scorecard criteria, weights, targets, and prior period.

Result

A scorecard sheet, review agenda, and improvement-request document with calculations and citations.

Quality criteria

• Denominators and exclusion rules are visible for every metric.
• Weighted score reconciles to component scores.
• Period comparison uses like-for-like definitions.
• Every recommendation links to a finding.

Instructions

Do not count missing delivery dates as on-time. Separate supplier-caused and internally caused exceptions when evidence permits. Use supplied weights and targets; if missing, report metrics without inventing a grade. Preserve order and case identifiers for traceability.

The review should make the population, calculation basis, and exception treatment understandable to a second operator. Preserve source identifiers in every working table, and state the effect of missing evidence on the decision. A reviewer must be able to reproduce each material result from the cited rows, clauses, dates, or policy rules. Where two sources disagree, show both values and explain which source was treated as authoritative.

Use the outputs as review workpapers: retain the source locator beside every material value, and keep planned action separate from completed evidence. The final document must identify the consequence of each gap for the relevant operational or control decision.

Adapt before use

• Map order, delivery, receipt, quality, price, and service fields.
• Add metric definitions, weights, targets, and exclusion rules.
• Define score bands, review cadence, and improvement-owner conventions.
