Assess Technology Resilience and Recoverability — RTO, RPO, and Disaster Recovery Readiness
(Chapter 127 of Technology Portfolio Management (TPM) Best Practices)
Executive Summary: Chapter Overview
IF4ITThe Bottom Line
Core Concepts
| Concept | Definition & Strategic Role |
|---|---|
| RTO and RPO | RTO is the maximum acceptable time a technology can be unavailable before the business impact becomes unacceptable; RPO is the maximum acceptable amount of data loss, measured in time, if the technology must be restored from backup. |
| Disaster Recovery Readiness | The current backup, redundancy, and failover posture of a technology, and whether recovery capability has actually been tested against target RTO and RPO — rather than assumed to work. |
Quick Q&A
Question: Why does resilience assessment need to be distinct from technical fitness or Rationalization Posture?
Question: What should be captured for every critical technology?

Overview
Technical fitness and Rationalization Posture tell an organization whether a technology is well-maintained and worth continued investment — but neither answers how quickly the organization needs it back after a disruption, or how much data loss it can tolerate if it fails. Technologies treated as equally resilient by default routinely turn out to have actual recovery capability badly mismatched to their true criticality — some over-invested in resilience they do not need, others critically under-protected.
Best Practice
Define a target Recovery Time Objective and Recovery Point Objective for every technology whose unavailability would carry meaningful operational, financial, regulatory, or reputational consequence, based on the criticality of its dependent applications rather than default assumptions or infrastructure convenience. Record current backup, redundancy, and failover posture, and track whether recovery capability has actually been tested against the target RTO and RPO — an untested recovery plan should be treated as an assumption, not a fact, until it is exercised. Use this data as an evidentiary input to enterprise business continuity and disaster recovery planning.

Benefit(s)
Explicit RTO and RPO capture ensures resilience investment is allocated according to actual business consequence rather than assumption or infrastructure convenience — critical technologies receive the recovery capability they require, and non-critical technologies are not over-invested in unnecessary redundancy. Testing recovery capability against target, rather than assuming it works, surfaces gaps before a real disruption does.
