SQALE Method • Code Quality Metrics • Refactoring ROI • Maintainability Index
3D Code Health Cube • Health Score: 0%
SQALE (Software Quality Assessment based on Lifecycle Expectations) is a method to assess technical debt. Ratings from A (< 2.5% TDR) to E (> 20% TDR).
TDR = Remediation Cost / Development Cost × 100. It measures the cost to fix issues vs the cost to build. < 5% is good, > 10% is concerning.
Based on code complexity, test coverage, and code smells. MI > 85 is excellent, 65-85 is good, < 65 needs attention.
Number of linearly independent paths through code. < 10 is simple, 10-20 is moderate, > 20 is complex and risky.
Like financial debt, technical debt slows development velocity. Each sprint, you lose productivity dealing with poor code quality.
When interest per sprint exceeds remediation cost amortized over expected code lifespan. Our calculator shows break-even point.
Indicators of deeper problems: long methods, large classes, duplicated code, dead code, etc. Not bugs but design issues that reduce maintainability.
"This calculator convinced our board to approve a $500K refactoring initiative. The ROI projection showing 15-sprint break-even was exactly what we needed. We've since improved from SQALE D to B."

"The priority matrix is gold! We focused on the high-ROI items first and reduced our TDR from 18% to 6% in 6 months. Velocity increased 40% as predicted."

Tech Lead, E-commerce
"As a CTO, I use this quarterly to track code health across 12 teams. The maintainability index and radar chart make perfect exec dashboard material. Highly recommended!"
