### Sustain Phase Appendices

The appendices bring the concepts discussed in **A Practitioner’s Guide to the “Sustain” Phase** into practical application.

The templates should be adapted to reflect the organisation’s size, complexity, regulatory environment, risk profile, governance structure, and operational resilience maturity.

#### Appendix Z: Glossary of Key Operational Resilience Terms

**Critical Business Service**  
A service whose disruption could result in intolerable harm to customers, the organisation, the market, or other relevant stakeholders.

**Operational Resilience**  
The ability of an organisation to prevent, adapt to, respond to, recover from, and learn from operational disruption while continuing to deliver critical business services.

**Impact Tolerance**  
The maximum level of disruption to a critical business service that the organisation is prepared to tolerate before intolerable harm occurs.

**Interconnection**  
A relationship or linkage between components involved in delivering a business service.

**Interdependency**  
A dependency between people, processes, technology, facilities, information, data, third parties, or other services where failure of one may affect another.

**Scenario Testing**  
A structured process for evaluating whether the organisation can continue delivering critical business services under severe but plausible disruption.

**Cultural Change**  
The process of embedding resilience behaviours, attitudes, accountability, and decision-making into normal organisational practice.

**Training and Awareness**  
Activities designed to develop knowledge, capability, competency, and preparedness for operational resilience responsibilities.

**Self-assessment**  
A structured internal evaluation of the design, implementation, effectiveness, and maturity of operational resilience arrangements.

**Independent Quality Review**  
An objective assessment conducted by a sufficiently independent and competent party to provide assurance over operational resilience.

**Residual Risk**  
The remaining level of risk after controls and mitigation measures have been applied.

**Remediation**  
Actions taken to address weaknesses, findings, vulnerabilities, or control deficiencies.

**Retesting**  
Testing conducted after remediation to determine whether the corrective action is effective.

**Continuous Improvement**  
The ongoing process of monitoring, assessing, challenging, improving, and revalidating operational resilience capability.
