Core Scoring Columns to Add to Your MyCNBox Sheet
Add these three dedicated columns next to each supplier's record. Use a numeric scale (e.g., 1-5 or 1-10) for consistency.
Calculating the Overall Supplier Rank
Add a fourth column: "Overall Score". Use a formula to calculate a weighted average based on your priorities. For instance:
Overall Score = (Reliability * 0.5) + (Communication * 0.2) + (QC Performance * 0.3)This example prioritizes Reliability (50%), then QC (30%), and Communication (20%). Adjust weights to fit your business needs. You can then sort your supplier list by this "Overall Score" column in descending order.
