Code Quality Improvement Workflows
Improving code quality requires systematic workflows that make quality visible and improvement achievable alongside regular feature work. GitScrum helps teams track quality initiatives, balance technical improvements with business deliverables, and measure the impact of quality investments over time.
Quality Workflow Structure
Quality Budget Allocation
SPRINT CAPACITY ALLOCATION:
┌─────────────────────────────────────────────────────────────┐
│ │
│ SPRINT CAPACITY (100 points): │
│ │
│ Features: 60-70% ████████████████████░░░░░░ │
│ Quality: 15-20% █████░░░░░░░░░░░░░░░░░░░░ │
│ Bug fixes: 10-15% ████░░░░░░░░░░░░░░░░░░░░░ │
│ Buffer: 5-10% ███░░░░░░░░░░░░░░░░░░░░░░ │
│ │
│ QUALITY BUDGET INCLUDES: │
│ • Refactoring │
│ • Test coverage improvements │
│ • Documentation │
│ • Technical debt reduction │
│ • Code review improvements │
└─────────────────────────────────────────────────────────────┘
Quality Task Types
QUALITY WORK CATEGORIES:
┌─────────────────────────────────────────────────────────────┐
│ CATEGORY │ EXAMPLES │
├─────────────────┼───────────────────────────────────────────┤
│ Refactoring │ • Extract common patterns │
│ │ • Improve naming and structure │
│ │ • Reduce complexity │
├─────────────────┼───────────────────────────────────────────┤
│ Testing │ • Add unit tests │
│ │ • Improve integration tests │
│ │ • Add edge case coverage │
├─────────────────┼───────────────────────────────────────────┤
│ Documentation │ • Code comments for complex logic │
│ │ • API documentation │
│ │ • Architecture decision records │
├─────────────────┼───────────────────────────────────────────┤
│ Tooling │ • Linting rules │
│ │ • CI/CD improvements │
│ │ • Developer experience │
└─────────────────────────────────────────────────────────────┘
Improvement Identification
Code Quality Metrics
METRICS TO TRACK:
┌─────────────────────────────────────────────────────────────┐
│ METRIC │ MEASURE │ TARGET │
├─────────────────────┼───────────────────┼───────────────────┤
│ Test Coverage │ Lines covered (%) │ > 80% │
│ Code Duplication │ Duplicate blocks │ < 3% │
│ Cyclomatic Complexity│ Avg per function │ < 10 │
│ Technical Debt Ratio│ Remediation time │ < 5% │
│ Code Smells │ Count │ Decreasing │
│ Bug Density │ Bugs per KLOC │ < 0.5 │
└─────────────────────────────────────────────────────────────┘
Hotspot Analysis
IDENTIFYING QUALITY HOTSPOTS:
┌─────────────────────────────────────────────────────────────┐
│ │
│ PRIORITIZE BY: │
│ │
│ Change Frequency × Complexity = Improvement Priority │
│ │
│ HIGH PRIORITY: │
│ Files changed often + high complexity │
│ → Biggest bang for buck in improvement │
│ │
│ LOWER PRIORITY: │
│ Files rarely changed + high complexity │
│ → Complex but stable, lower risk │
│ │
│ Track in GitScrum: │
│ • Create quality task per hotspot │
│ • Link to bug history │
│ • Tag with "quality-hotspot" │
└─────────────────────────────────────────────────────────────┘
Quality Improvement Process
Boy Scout Rule
INCREMENTAL IMPROVEMENT:
┌─────────────────────────────────────────────────────────────┐
│ │
│ "Leave the code better than you found it" │
│ │
│ WHEN WORKING ON A FEATURE: │
│ │
│ Small improvements (no extra task needed): │
│ • Rename unclear variable │
│ • Extract small method │
│ • Add missing test │
│ • Fix obvious code smell │
│ │
│ Larger improvements (create task): │
│ • Major refactoring │
│ • New test suite │
│ • Architecture changes │
│ │
│ Track patterns in GitScrum: │
│ • Note quality improvements in task comments │
│ • Create follow-up tasks for larger work │
└─────────────────────────────────────────────────────────────┘
Quality Sprints
PERIODIC QUALITY FOCUS:
┌─────────────────────────────────────────────────────────────┐
│ │
│ QUARTERLY QUALITY SPRINT: │
│ Every 4th sprint, increase quality budget to 40% │
│ │
│ ACTIVITIES: │
│ • Address accumulated tech debt │
│ • Major refactoring initiatives │
│ • Test suite improvements │
│ • Tooling and automation │
│ • Documentation catch-up │
│ │
│ PLANNING: │
│ 1. Review quality metrics from past quarter │
│ 2. Identify highest-impact improvements │
│ 3. Create detailed improvement tasks │
│ 4. Communicate plan to stakeholders │
│ 5. Execute with full team focus │
