Maintaining consistent quality and reliable partnerships is crucial in global sourcing. KAKOBUY’s custom spreadsheet provides a powerful, data-driven method for evaluating and ranking suppliers. By focusing on three key performance indicators (KPIs) and assigning weighted scores, businesses can objectively identify top-performing sellers and proactively manage their supply chain.
The Three Core Performance Metrics
Our ranking system is built on measurable criteria that directly impact sourcing success:
- Inspection Success Rate (Weight: 50%): The percentage of products passing initial quality control (QC) inspection. This is the primary indicator of product quality and manufacturing consistency.
- Communication Speed (Weight: 30%): The average response time (in hours) to critical queries. This measures reliability and collaboration efficiency.
- Delivery Punctuality (Weight: 20%): The percentage of orders shipped or delivered by the agreed-upon date. This assesses logistical reliability.
Building the Ranking System in Your Spreadsheet
Follow these steps to implement a weighted scoring model:
-
Create a Data Table: Set up a table for each seller with columns for:
- Seller Name/ID
- Inspection Success Rate (%)
- Avg. Communication Response Time (Hours)
- On-Time Delivery Rate (%)
- Normalize the Data: Convert all metrics to a 0-100 scale for fair comparison.
- For Inspection Success RateOn-Time Delivery Rate, the percentage itself is the score (e.g., 95% = 95 points).
- For Communication Speed, create a scale. For example: Response in <12 hours = 100 points, <24 hours = 80 points, <48 hours = 60 points, and so on.
-
Calculate the Weighted Score: Use this formula for each seller:
Weighted Score = (Inspection Rate * 0.50) + (Communication Score * 0.30) + (Delivery Rate * 0.20) - Generate the Ranking: Sort your seller list by the Weighted Score
Practical Example
Consider two suppliers:
| Seller | QC Rate (50%) | Comm Score (30%) | Delivery (20%) | Weighted Total |
|---|---|---|---|---|
| Seller A | 98% → 98 | Fast (<12h) → 100 | 95% → 95 | (98*0.5)+(100*0.3)+(95*0.2) = 98.0 |
| Seller B | 85% → 85 | Slow (>48h) → 50 | 99% → 99 | (85*0.5)+(50*0.3)+(99*0.2) = 78.8 |
Despite Seller B's excellent delivery, Seller A's superior quality and communication earn a much higher overall rank.
Benefits and Strategic Application
Implementing this system transforms subjective assessment into objective strategy:
- Data-Driven Decisions: Allocate more business to top-ranked sellers to reduce risk.
- Proactive Management: Identify sellers with declining scores for corrective discussions.
- Performance Benchmarking: Set clear, measurable KPIs for all suppliers during contract negotiations.
- Process Transparency: The clear scoring methodology ensures fair and consistent evaluation across your team.
Conclusion
The KAKOBUY spreadsheet ranking method empowers buyers to move beyond instinct, using a clear, quantitative framework to evaluate seller performance. By regularly updating and reviewing this scorecard, businesses can foster stronger supplier relationships, minimize quality issues, and build a more resilient and high-performing supply chain.
