Supplier evaluation

Definition

Supplier evaluation measures how well a supplier performs against agreed criteria (quality, on-time delivery, price competitiveness, service and compliance), both when selecting and when reviewing incumbents. Scorecards make performance objective, support renewal or exit decisions and feed continuous improvement.

Example

A logistics firm scores carriers monthly on on-time delivery and damage rate; persistent underperformers lose volume at renewal.

Why this is a business risk

Without structured evaluation, renewal decisions are made subjectively or by inertia, retaining underperforming suppliers that drain value and expose operations to quality and compliance risk. Equally, poor selection at award time, without criteria, increases the chance of engaging a supplier that cannot deliver.

How to manage it

• Define evaluation criteria and weightings before selecting a supplier, not after, to prevent post-hoc justification.
• Capture performance data systematically throughout the contract, not only at renewal time.
• Share scorecard results with the supplier to drive improvement and document their response.
• Use evaluation outcomes directly in renewal, renegotiation and exit decisions to close the feedback loop.
• Include SLA-breach data and delivery milestone performance in evaluations, not only commercial criteria.
