Vendor Performance Management: KPIs and Best Practices

Vendor Performance Management involves setting clear expectations, measuring supplier outcomes, and tying actions to financial impact. It translates business strategy into measurable targets that procurement, operations, quality, and finance teams can administer with confidence. Core KPIs include on-time-in-full (OTIF), fill rate, lead-time adherence, defects per million (PPM), price variance, invoice accuracy, and ESG compliance. Each metric ladders to four key outcomes: lower total landed cost, reliable service, managed risk, and regulatory or contract compliance. Governance relies on a RACI model where procurement owns commercial levers, quality manages nonconformance, operations tracks service levels, and finance validates results. Scorecards should mirror contract SLAs, with clear thresholds, remedies, and incentives. Data collection starts with six objects—PO, ASN, receipt, invoice, nonconformance, contract—and requires master-data quality. Normalization by criticality and volume ensures small suppliers do not mask strategic performance. Regular reviews (monthly ops, quarterly exec, annual strategy) and joint business reviews drive continuous improvement.
