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 │

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 │
