Data reveals patterns. In the world of procurement and sourcing, understanding these patterns is key to building a reliable supply chain. This guide shows you how to leverage the ACBuy Spreadsheet to track average Quality Control (QC) performance by seller category, empowering you to identify consistently high-performing partners and make more informed purchasing decisions.
The Power of Tracking Average QC Performance
Simply looking at individual QC pass/fail reports offers a limited view. The true insight lies in aggregating data over time to establish performance trends. By calculating and monitoring the average QC performance for each seller or seller category, you can move from reactive problem-solving to proactive supplier management. This analysis helps answer critical questions: Is a supplier improving? Are there seasonal dips in quality? Which categories have the most reliable partners?
Step-by-Step: Tracking Performance by Seller Category
Follow this structured approach within your ACBuy Spreadsheet data to uncover vital trends.
Step 1: Data Preparation & Categorization
Ensure your spreadsheet has consistent columns such as Seller Name, Seller CategoryQC Date, QC ResultOrder ID. Consistent categorization is crucial for accurate grouping.
Step 2: Calculate the Core Metric
Create a new calculation for each transaction or batch. If using Pass/Fail, assign a numerical value (e.g., Pass=1, Fail=0). The key metric is the QC Pass Rate, typically calculated as:
QC Pass Rate = (Number of QC Passes) / (Total Number of QC Checks)
Step 3: Aggregate by Seller Category
Use spreadsheet functions like PIVOT TABLESUMIFS/AVERAGEIFSSeller Category:
- Total Number of Orders/QC Checks
- Number of QC Passes
- Average QC Pass Rate (Percentage)
- Trend over a defined period (e.g., last quarter vs. previous quarter)
Step 4: Visualize the Trends
