Managing supplier quality on KAKOBUY requires a data-driven approach. Consistently ranking your sellers based on their Quality Control (QC) performance is crucial for building a reliable and efficient supply chain. This guide explains how to use the KAKOBUY Performance Spreadsheet to assign weighted scores and create a clear, actionable seller ranking.
The Three Pillars of QC Performance
Our system evaluates sellers based on three core performance indicators, each representing a critical aspect of a successful transaction:
- Inspection Success Rate (Quality):
- Communication Speed (Responsiveness):
- Delivery Punctuality (Logistics):
- Communication Speed (Responsiveness):
Setting Up Your KAKOBUY Performance Spreadsheet
Create a spreadsheet with the following columns for each seller: Seller ID/Name, Total Orders, Passed Inspections, Failed Inspections, Avg. Response Time (Hours), On-Time Deliveries, and Late Deliveries.
Step 1: Calculate Raw Metrics
First, compute the basic performance ratios for each seller:
- Inspection Success Rate
- Communication Score48h = 50)
- Delivery Punctuality Rate
Step 2: Assign Weighted Importance
Not all pillars are equally important for every business. Assign a weight percentage to each category. The total must equal 100%. A common example for quality-centric businesses is:
| Performance Pillar | Weight | Rationale |
|---|---|---|
| Inspection Success Rate | 50% | Product quality is the highest priority. |
| Communication Speed | 30% | Responsiveness prevents and solves problems. |
| Delivery Punctuality | 20% | Timeliness impacts inventory and planning. |
Step 3: Calculate the Weighted Final Score
For each seller, calculate the weighted score using this formula:
Final Score = (Inspection Rate * 0.50) + (Communication Score * 0.30) + (Punctuality Rate * 0.20)
Example: Seller A has 95% Inspection, 80 Communication Score, 90% Punctuality.
Final Score = (95 * 0.50) + (80 * 0.30) + (90 * 0.20) = 47.5 + 24 + 18 = 89.5
Step 4: Rank and Tiers
Sort your seller list by the Final Score in descending order. Establish clear tiers for quick assessment:
- Tier A (90-100):
- Tier B (75-89):
- Tier C (60-74):
- Tier D (Below 60):
- Tier B (75-89):
Conclusion & Continuous Improvement
