In the competitive world of e-commerce and global sourcing, maintaining consistent product quality is paramount. For businesses leveraging platforms like MyCNBox, understanding the long-term performance of your suppliers is a key strategic advantage. This guide explains how you can use the MyCNBox Spreadsheet

Why Track QC Approval Rates Chronologically?

Spot-checking a single inspection report only gives a snapshot. To build a true picture, you need to analyze data across weeks and months. Tracking approval rates over time helps you:

  • Identify Consistency (or Lack Thereof):
  • Predict Future Performance:
  • Make Data-Driven Sourcing Decisions:
  • Pinpoint Seasonal or Production Issues:

Structuring Your MyCNBox Data for Analysis

Effective time-based analysis starts with well-organized data. Ensure your spreadsheet includes these essential columns for each QC inspection:

Column Header Description Essential for Time Tracking
Inspection Date The date the QC check was performed (e.g., 2023-10-26). Yes - The primary time anchor.
Seller/Factory Name The identifier for your supplier. Yes - For segmenting trends by seller.
Product SKU/ID The specific product inspected. Yes - For analyzing trends per item.
QC Result Typically "Approved", "Rejected", or "Approved with Remarks". Yes - The core metric for calculation.
Major/Minor Defects Counts of critical and non-critical issues found. Optional - Adds depth to the analysis.
Order Quantity Total units in the order. Optional - For weighting data if needed.

Step-by-Step: Analyze Approval Rates Across Months

Step 1: Consolidate and Clean Your Data

Gather all QC reports from the MyCNBox platform into a single master spreadsheet. Standardize the entries: ensure seller names are spelled consistently, dates are in the same format (use YYYY-MM-DD), and results use the same categories.

Step 2: Create a Time Frame Reference

Create a separate column to extract the Month-Year=TEXT(A2, "YYYY-MM")

Step 3: Calculate Monthly Approval Rates

Use a Pivot Table to summarize the data:

  1. Select your data range.
  2. Insert a Pivot Table.
  3. Drag Month-Year
  4. Drag Seller Name
  5. Drag QC Result
  6. Filter the Value field to show only counts for "Approved".
  7. Add a calculated field or copy the counts to a new sheet to calculate the Approval Rate(Number of Approved Inspections / Total Inspections that Month) * 100.

Step 4: Visualize the Trends with Charts

Select your monthly approval rate data and insert a Line ChartColumn Chart. A line chart is excellent for showing trends over continuous time.

  • Chart Title:
  • X-Axis:
  • Y-Axis:
  • Plot multiple lines for different sellers on the same chart to compare their reliability visually.

Step 5: Interpret the Data and Take Action

Analyze the chart and calculated rates:

  • Upward Trend:
  • Downward Trend:
  • High Volatility:
  • Benchmarking:
