A disruption scenario designed to challenge an important business service within the operational-resilience framework.
Why the distinction matters
The scenario should be demanding and credible for the service being tested. Document affected dependencies, duration, constraints and the evidence needed to assess the result. Avoid defining success so narrowly that the exercise cannot reveal a weakness.
In the working file
Illustrative example
A test combines a provider outage with unavailable records and measures whether the alternative process can handle the resulting backlog.
Use the term in context
Record the legal entity, activity, period and applicable source alongside the term. A familiar label does not remove the need to establish scope. Our operating playbook connects this definition to a practical process.
