Review Stakeholder Feedback: Understanding the nature of the negative feedback is the first step.

Analyze Scorecard Metrics: If the scorecards have been positive, but the feedback is negative, it suggests a misalignment.

Adjust Metrics Accordingly: The scorecards should be updated to align with the new requirements to ensure they accurately reflect supplier performance.
