Defect Per Million Opportunity Rates for Major Defect Types

Manufacturing quality data presents defect per million opportunity (DPMO) occurrences for the most common defect types. The dataset is a single 5.5 KB Excel file created by Ahmed M. Abed and last updated in April 2026.

Use Cases

• Benchmark DPMO rates across different defect types to identify primary failure modes.
• Calculate process capability indices (Cp, Cpk) using DPMO data for quality control.
• Prioritize root cause analysis and corrective actions based on the highest DPMO defect categories.
• Track quality improvement over time by monitoring changes in DPMO for specific defect types.

Strengths

• Openly licensed under CC-BY-4.0 for broad reuse.
• Data is structured in a tabular Excel (XLS) format for straightforward analysis.

Limitations

• Dataset is extremely small at 5.5 KB, indicating very limited scope and likely few records.
• Specific row count, column names, and temporal or geographic context are unknown, limiting reproducibility.
