Step-by-Step: Building the Rating System
Here’s how to add a powerful, yet simple, supplier scorecard to your existing MyCNBox sourcing spreadsheet.
Step 1: Define Your Rating Categories & Scale
First, add new columns to your supplier list sheet for the following core categories. Use a consistent numeric scale (e.g., 1-5 or 1-10).
| Column Header | Description | Sample Criteria (Scale: 1-Poor to 5-Excellent) |
|---|---|---|
| Reliability Score | Meets deadlines and fulfills order terms. | 1: Consistently late. 3: Occasionally late. 5: Always on time or early. |
| Communication Score | Clarity, speed, and proactivity of communication. | 1: Unresponsive/poor English. 3: Adequate. 5: Proactive, clear, and prompt. |
| QC Performance Score | Quality of goods received vs. samples/expectations. | 1: Major defects/common issues. 3: Minor, acceptable issues. 5: Matches sample perfectly. |
Step 2: Add Calculation Columns
Add columns to calculate the total and average score. This will be your key ranking metric.
Total Score: Formula:=SUM([Reliability Cell], [Communication Cell], [QC Cell])Average Score: Formula:=AVERAGE([Reliability Cell], [Communication Cell], [QC Cell])
Step 3: Implement a Ranking Column
Add a RankRANK.EQAverage ScoreTotal Score.
Example Formula in cell for Supplier 1:=RANK.EQ([Average Score Cell], [Entire Average Score Column Range], 0)
The supplier with the highest average score will receive rank 1.
Step 4: (Optional) Add Conditional Formatting
Use color scales on your score columns to create a visual "heat map." For instance, set scores of 4-5 to green, 3 to yellow, and 1-2 to red. This lets you spot strengths and weaknesses at a glance.
