Step 8 Final Status Report

✅ Objective Achieved

Successfully refactored the KPI correlation analysis codebase to share code between Gradio and CLI interfaces.

Test Results Summary

All Tests Passed ✅

1. test_refactoring.py - Core module functionality verification
2. test_step3.py - Correlation analysis with partial data
3. test_plotting.py - Plot generation functionality
4. test_excel_conversion.py - Excel to CSV conversion
5. test_correlation_analysis.sh - Shell script integration test
6. example_usage.sh - Example commands verification

Key Improvements

• Zero code duplication between interfaces
• Single source of truth for analysis logic
• Backward compatible - all existing scripts work unchanged
• Enhanced Gradio app with command-line arguments
• Better organized codebase with clear separation of concerns

Architecture Summary

Before Refactoring:
- kpi_correlation_app.py (275 lines with duplicate analysis code)
- analyze_correlations_v2.py (416 lines with duplicate analysis code)

After Refactoring:
- kpi_correlation_app.py (239 lines, UI-focused)
- analyze_correlations_v2.py (269 lines, CLI-focused)
- correlation_analysis_core.py (209 lines, shared logic)

Command Examples

Gradio Interface (Enhanced)

# With custom scores file
python3 kpi_correlation_app.py --scores-file /path/to/scores.csv --port 8080

CLI Interface (Unchanged)

# With plotting
python3 analyze_correlations_v2.py -k kpi.csv -s scores.csv -p -o results.yaml

Files Created/Modified

Created

• correlation_analysis_core.py - Core analysis module
• test_refactoring.py - Refactoring test
• step8_summary.md - Detailed summary
• step8_final_status.md - This file

Modified
