Quality Control (QC) data holds the key to supply chain excellence, yet raw data is often overwhelming. A pivot table is your most powerful tool to transform this data into actionable intelligence. This guide demonstrates how to quickly identify patterns, recurring failures, and high-performing vendors.
Step 1: Structure Your Raw QC Data
Effective analysis starts with well-organized source data. Ensure your QC log has clear columns such as:
- Inspection Date
- Vendor Name
- Product SKU/ Batch #
- Defect Type
- Defect Severity
- Inspection Result
- Inspector
- Defect Severity
Step 2: Create Your Pivot Table
In your spreadsheet software (e.g., Excel, Google Sheets):
- Select your entire QC dataset.
- Navigate to Insert Pivot Table.
- Place the pivot table in a new worksheet for clarity.
