Identifying Gaps
Coverage Analysis
GAP ANALYSIS:
┌─────────────────────────────────────────────────────────────┐
│ │
│ COVERAGE TYPES: │
│ ─────────────── │
│ │
│ ✅ COVERED (Safe): │
│ Multiple team members can handle it │
│ No single point of failure │
│ Can take vacation without risk │
│ │
│ ⚠️ BUS FACTOR RISK: │
│ One person holds all knowledge │
│ Team blocked if they're out │
│ Critical to cross-train │
│ │
│ 🔴 GAP: │
│ No one has adequate skill │
│ Blocking team capability │
│ Need training or hiring │
│ │
│ ─────────────────────────────────────────────────────────── │
│ │
│ GAP REPORT: │
│ ┌─────────────────────────────────────────────────────────┐│
│ │ TEAM: Product Squad ││
│ │ DATE: January 2025 ││
│ │ ││
│ │ CRITICAL GAPS: ││
│ │ 🔴 Security: No expert ││
│ │ Impact: Security reviews delayed ││
│ │ Action: Training program + external review ││
│ │ ││
│ │ BUS FACTOR RISKS: ││
│ │ ⚠️ AWS: Only Alex (★★★) ││
│ │ Impact: Infra work blocked when Alex out ││
│ │ Action: Jordan pairs on next AWS work ││
│ │ ││
│ │ ⚠️ CI/CD: Only Sam (★★★★) ││
│ │ Impact: Pipeline issues hard to debug ││
│ │ Action: Document current setup, share knowledge ││
│ │ ││
│ │ EMERGING NEEDS: ││
│ │ 📋 GraphQL: Team average ★★ ││
│ │ Context: API migration planned Q2 ││
│ │ Action: Training before migration starts ││
