Why this module exists. A BCDR plan that has never been tested is a hypothesis. Recovery testing — tabletop, functional, full failover — is what turns the plan into a verified capability. This module covers the four testing tiers, what each catches, and the cadence that maintains real recovery readiness.

Why this module exists. Indian enterprises that test their DR architecture annually consistently outperform those that test it on the day of incident. The difference is operational muscle memory. This module covers building it.

The four testing tiers

Tier Disruption What it tests
Tabletop None Plan logic, role clarity, decision-making
Walk-through None Detailed step verification without execution
Functional / Simulation Partial — isolated environment Technical recovery procedures, RTO verification
Full failover Significant — production switched to DR End-to-end capability, real-world dependencies
