A Guide to Analyzing Quality Consistency and Seller Reliability Trends
Introduction
For businesses utilizing MyCNBoxQC Approval Rates
Setting Up Your Tracking Spreadsheet
Structure your spreadsheet to capture the essential dimensions of your QC data. Key columns should include:
- Month/Period:
- Seller Name/ID:
- Total Quantity Inspected:
- Quantity Approved:
- Quantity Failed:
- Approval Rate (%):
- Major Defect Categories:
- Seller Name/ID:
Populate this sheet monthly with data from your MyCNBox QC reports.
Analyzing Trends: Key Calculations & Visualizations
1. Monthly Approval Rate Trend
Calculate the overall approval rate for each month. Plot this on a line chart
2. Seller-Specific Trend Analysis
Use a pivot table
3. Defect Driver Analysis
Track the frequency of major defect categories over time. A rising trend in a specific defect (e.g., "electrical safety") points to a systemic manufacturing issue that needs addressing.
Interpreting the Data for Action
The true value lies in interpreting these trends:
| Trend | Possible Interpretation | Potential Action |
|---|---|---|
| Gradual decline in a seller's rate | Declining process control or cost-cutting at the factory. | Initiate a corrective meeting, increase inspection frequency, or source backup suppliers. |
| Sudden drop across multiple sellers | Possible issue with your QC standards, or a raw material market problem. | Review QC clarity with your team and communicate with suppliers collectively. |
| Consistent high performance | A reliable partner. Signals trust and reduces required inspection intensity. | Consider reward strategies or negotiated pricing for sustained quality. |
