Transform raw failure data into actionable insights using charts and heatmaps to spot trends and drive continuous improvement.
For e-commerce platforms like KAKOBUY, managing product quality is paramount to customer satisfaction and brand reputation. However, Quality Control (QC) failure data trapped in static lists or reports is hard to analyze. A well-designed Spreadsheet Dashboard
Building Your QC Failure Dashboard: A Step-by-Step Guide
Step 1: Consolidate & Structure Your QC Data
Start with a clean, structured dataset in your spreadsheet (e.g., Google Sheets or Excel). Each row should represent a failed inspection, with columns for key attributes:
- Date/Time:
- Product ID/Category:
- Supplier/Batch:
- Failure Type:
- Severity Level:
- Inspector/Station:
- Product ID/Category:
Step 2: Create Pivot Tables for Dynamic Analysis
Use Pivot Tables to summarize your data dynamically. Key summaries include:
- Failure count by Product Category.
- Trend of failures over Time
- Failure frequency by SupplierFailure Type.
These tables become the data engines for your visual charts.
Step 3: Visualize Patterns with Key Charts
Convert your Pivot Tables into visual formats for instant analysis.
A. Bar/Column Charts: Top Failure Categories
Create a bar chart showing failure counts by Product CategoryFailure Type. This instantly highlights which areas need the most urgent attention.

B. Line Charts: Track Failure Trends Over Time
Plot a line chart of daily or weekly failure counts. Overlay it with major events like a new supplier shipment or process change.

C. Pie/Donut Charts: Breakdown by Severity or Supplier
Use a pie chart to show the proportion of Critical vs. Major vs. Minor
Step 4: Create a Heatmap for Advanced Pattern Detection
This is your most powerful tool for identifying hidden correlations.
