1.7 Risk Assessment¶
1.7.1 Technical Risks¶
| Risk ID | Risk Description | Probability | Impact | Mitigation |
|---|---|---|---|---|
| RISK-001 | Legacy device incompatibility | High | High | Phased hardware refresh |
| RISK-002 | ISE learning curve impacts deployment | Medium | High | Pre-deployment training |
| RISK-003 | Application breakage during migration | Medium | Critical | Extensive UAT, staged rollout |
| RISK-004 | Authentication failures at cutover | Medium | High | Parallel run period |
| RISK-005 | Insufficient bandwidth for VXLAN overhead | Low | Medium | Bandwidth assessment |
| RISK-006 | DNAC-ISE integration issues | Medium | High | Lab validation |
| RISK-007 | Skills gap delays deployment | High | Medium | Training program |
| RISK-008 | Vendor support escalation delays | Low | Medium | TAC priority contract |
