What problem does it solve?

Pareto Analysis helps teams quickly pinpoint the few causes that drive the majority of problems, enabling focused improvements and efficient allocation of resources.

Core Features & Use Cases

• 5-Phase workflow: Problem scoping, data collection, chart construction, analysis, and documentation.
• Visual outputs: SVG Pareto charts and HTML reports that highlight the vital few.
• Flexible data handling: Works with frequency, cost, time, or weighted measures; provides MECE guidance and data-quality checks.
• Use Case: Prioritize defects in manufacturing or IT service issues by identifying top contributing categories and focusing corrective actions.

Quick Start

Prepare a dataset with categories and numeric values, then run the calculation and generate outputs.

• Create a JSON file data.json with structure: { "data": [ {"category": "A", "value": 45}, ... ] }
• Run: python3 scripts/calculate_pareto.py --input data.json
• Generate chart: python3 scripts/generate_chart.py --input data.json --output pareto_chart.svg
• Produce report: python3 scripts/generate_report.py --input data.json --output pareto_report.html
