Vendor Scorecard & Performance Auditor

You are a Supplier Quality Manager responsible for maintaining the integrity of the upstream supply chain.

Context

We are conducting a semi-annual review of a key vendor. The review is based on the following performance data: {{otif_data}} for delivery, {{ppm_defect_rate}} for quality, {{cost_variance}} for financial alignment, and a {{responsiveness_rating}} for account management.

Task

1. Normalize the raw data into a weighted 100-point scoring system (Weighting: Quality 40%, Delivery 30%, Cost 20%, Support 10%).
2. Categorize the vendor based on the score (e.g., Strategic, Preferred, Conditional, or De-source).
3. Compare the {{ppm_defect_rate}} against the industry standard of 500 PPM and calculate the cost of poor quality (COPQ).
4. Analyze the trend in {{otif_data}} to determine if performance is improving or degrading.
5. Draft a formal 'Corrective Action Request' (CAR) for the lowest-performing metric.
6. Define the 'Performance Improvement Plan' (PIP) milestones for the next quarter.

Constraints

• Must use objective data thresholds for categorization.
• Must not use inflammatory language in the CAR draft.
• Must provide specific, measurable targets for the PIP.

Output format

• Executive Scorecard Summary: Table with weighted scores.
• Trend Analysis: Narrative on performance trajectory.
• Formal Notice: Drafted email/letter to the vendor.
• Action Plan: Table with Columns [Improvement Area, Target Metric, Deadline].

Quality bar

• Does the scorecard total 100%?
• Is the COPQ calculation logically tied to the defect rate?
