│ │ Day 5 of 10: 25 points done, 25 remaining ││
│ │ Velocity: 5 points/day ││
│ │ Projected: 5 more days = finish on day 10 ✓ ││
│ │ ││
│ │ Warning indicators: ││
│ │ 🟢 On track: Projection within sprint ││
│ │ 🟡 At risk: Projection 1-2 days late ││

├─────────────────────────────────────────────────────────────┤
│ │
│ FALLING BEHIND SCHEDULE: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Day 5 check: 15 points done, should be 25 ││
│ │ ││
│ │ Immediate actions: ││
│ │ 1. Identify blockers in daily standup ││
│ │ 2. Remove low-priority items from sprint ││
│ │ 3. Break large tasks into smaller deliverables ││
│ │ 4. Add help for overloaded team members ││
│ │ ││
│ │ Communication: ││
│ │ • Update stakeholders on adjusted expectations ││
│ │ • Be transparent about what will/won't ship ││
│ │ • Focus on sprint goal, not all tasks ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ SCOPE INCREASING: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Burndown shows work added mid-sprint ││
│ │ ││
│ │ Immediate actions: ││
│ │ 1. Stop adding work to current sprint ││
│ │ 2. New requests go to backlog only ││
│ │ 3. If critical, swap out equal-sized item ││
│ │ ││
│ │ Prevention: ││
│ │ • Clear sprint commitment at planning ││
│ │ • Stakeholder education on sprint boundaries ││
│ │ • Emergency-only additions with trade-offs ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ WORK NOT CLOSING: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Flat burndown despite work being done ││
│ │ ││
│ │ Root causes to investigate: ││
│ │ • Are tasks too large? Split them ││
│ │ • Is testing bottleneck? Add QA capacity ││
│ │ • Are reviews delayed? Set review SLA ││
│ │ • Not updating board? Daily standup reminder ││
│ │ ││
│ │ Process fix: ││
│ │ • Definition of Done checklist on each task ││
│ │ • Move to Done only when truly complete ││
│ │ • Daily board hygiene review ││

┌─────────────────────────────────────────────────────────────┐
│ MAXIMIZING BURNDOWN VALUE │
├─────────────────────────────────────────────────────────────┤
│ │
│ DAILY REVIEW: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Morning check (2 minutes): ││
│ │ • Glance at burndown before standup ││
│ │ • Note any concerning patterns ││
│ │ • Prepare questions for team ││
│ │ ││
│ │ Standup integration: ││
│ │ • Share screen with burndown visible ││
│ │ • "We're 10% behind ideal—what's blocking?" ││
│ │ • Focus discussion on completing, not starting ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ ACCURATE DATA: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Burndown is only useful with accurate data: ││
│ │ ││
│ │ ✅ Update task status when work actually changes ││
│ │ ✅ Estimate all tasks before sprint starts ││
│ │ ✅ Re-estimate if scope changes significantly ││
│ │ ✅ Close tasks same day they're completed ││
│ │ ││
│ │ ❌ Batch updates at end of day/week ││
│ │ ❌ Leave tasks "in progress" when blocked ││
│ │ ❌ Add unestimated work to sprint ││
│ └─────────────────────────────────────────────────────────┘│
│ │
│ SPRINT RETROSPECTIVE USE: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ Review burndown in retrospective: ││
│ │ ││
│ │ Questions to ask: ││
│ │ • Where did actual diverge from ideal? ││
│ │ • What caused the divergence? ││
│ │ • How can we prevent it next sprint? ││
│ │ ││
│ │ Track patterns over multiple sprints: ││
│ │ • Do we always start slow? ││
│ │ • Do we always add scope? ││
│ │ • Does the same phase always bottleneck? ││
