Structuring Your GTBuy Analysis Spreadsheet
Create a sheet with the following columns for each order:
| Seller Name | Order ID | Order Date | Promised Completion Date | Actual Completion Date | QC Pass Rate (%) | Major Issues Found | Comm. Response Time (hrs) | Comm. Rating (1-5) | Notes |
|---|---|---|---|---|---|---|---|---|---|
| Populate with data from each transaction for analysis. | |||||||||
How to Analyze the Data
2. QC Accuracy Scoring
Use the QC Pass Rate to create a consistency score. For example:
- 95-100% Pass Rate: High Performer
- 85-94% Pass Rate: Stable Performer
- Below 85%: High-Risk Seller
Cross-reference "Major Issues" notes to understand the severity of failures.
3. Communication Evaluation
A fast response time with a low rating indicates quick but unhelpful communication. Ideal sellers combine low response times (e.g., <24 hrs)high ratings (4-5). Flag sellers with high response times and low ratings.
