In the world of B2B sourcing, data-driven decisions are paramount. For procurement teams using platforms like BBDBuy, consistently evaluating supplier performance is key to managing risk and ensuring smooth operations. Two of the most critical metrics are QC Approval PercentageShipping Accuracy. This guide will show you how to transform raw supplier data into clear, actionable timeline charts using standard spreadsheet software like Microsoft Excel or Google Sheets.
Why Visualize These Metrics?
Tracking numbers in a table is one thing; seeing them plotted over time is another. Charts instantly reveal trends, highlight problems, and confirm improvements that raw data can obscure. A supplier's "95% QC pass rate"
1. Structuring Your Data
Begin with a well-organized data table. Each row should represent a specific time period (e.g., a week or a month), and columns should track your key metrics.
| Month | Orders Received | QC Passed | QC Pass % | On-Time Shipments | Shipping Accuracy % |
|-----------|----------------|-----------|-----------|-------------------|---------------------|
| Jan-2024 | 150 | 144 | 96.0% | 142 | 94.7% |
| Feb-2024 | 165 | 159 | 96.4% | 158 | 95.8% |
| Mar-2024 | 178 | 169 | 94.9% | 160 | 89.9% |
| Apr-2024 | 190 | 182 | 95.8% | 185 | 97.4% |
Columns like QC Pass %Shipping Accuracy %QC Pass % = (QC Passed / Orders Received) * 100.
