    Short answer

    Code quality cannot be evaluated by subjective personal opinion. Software teams rely on objective maintainability metrics, code coverage standards, static analysis rules, and technical debt indicators.

    Core Code Quality Metrics:

    MetricWhat It MeasuresTarget Threshold
    Cyclomatic ComplexityNumber of decision paths in a functionKeep below 10 per method
    Test CoveragePercentage of code lines covered by automated tests75% - 85% coverage
    Duplicated CodePercentage of duplicated code blocksKeep below 3%
    Maintainability IndexComposite metric of code readability and complexityGrade A / > 80 score

    Code Quality Checklist

    • [ ] Track cyclomatic complexity in static analysis tools
    • [ ] Enforce automated test coverage thresholds in CI/CD
    • [ ] Conduct regular technical debt refactoring sprints
