Make the intended outcome clear
Resilience is meaningful in relation to a service, its context and acceptable performance. TAR encourages teams to consider consequences across six connected domains.
Operational effectiveness
Keep asset-supported services within acceptable performance limits.
Safety & integrity
Protect people and the integrity of assets and their operating environment.
Security & trust
Support trustworthy information, systems and decisions.
Sustainability & adaptation
Respond to environmental change and consider resource use over time.
Compliance & assurance
Maintain evidence for relevant obligations and accountable decisions.
Lifecycle value & adaptability
Consider long-term value and the ability to adapt as needs change.
Evidence matters
Improvement should be supported by evidence appropriate to the decision. A checklist, a model or an unexplained score is not by itself proof that resilience improved.
