Cascading failure
A failure in which an initial disturbance at one subsystem propagates through one or more tightly coupled interfaces to affect additional subsystems, with each step reinforcing rather than containing the original disturbance, often driven by an unrecognized positive feedback loop running across interfaces that were never isolated from one another. (see Topic 3.6) treats cascading failure design in depth.
Defined in 4 GAGE programs, which carry 4 distinct definitions of it. The wording above is taught in Engineering Judgment and Professional Formation.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
A failure in which an initial disturbance at one subsystem propagates through one or more tightly coupled interfaces to affect additional subsystems, with each step reinforcing rather than containing the original disturbance, often driven by an unrecognized positive feedback loop running across interfaces that were never isolated from one another. (see Topic 3.6) treats cascading failure design in depth.
A failure pattern in which one component's outage produces stress or failure in a dependent component, often surfacing as an outage that appears larger or more widespread than its original trigger.
OWASP's ASI08; a wrong or malicious agent action that propagates through a multi-step workflow or multi-agent system with escalating impact. The Snowball leg of REINS.
a failure at an early step in a multi-step workflow that propagates, uncaught, through later steps rather than being detected and corrected.

Where it shows up at work
A definition is where Cascading failure starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.
Plans for a vendor failure, an unsafe model change or a suspended service: rollback, manual fallback, data export and safe decommissioning.
One lesson on this page teach it as a primary outcome.
Understands prompt injection, data poisoning, model theft, insecure integrations and excessive agent privileges, and the controls that reduce each.

Designs tests for factuality, robustness, fairness, safety and abuse resistance with rubrics, baselines and thresholds, and says what a score misses.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: DORA; NIS2; NIST AI RMF MANAGE 4; OWASP Top 10 for LLM Applications.
One interview question about it
Your AI vendor shuts down next month. What was in your continuity and exit plan, and what did you fail to plan for?
Asked of candidates for ai resilience, continuity and exit planning. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Cybersecurity and IT carries it as a claim to back up: Continuity and recovery planning are part of the job.
- A computer science or software engineering degree carries it as a claim to back up: Security fundamentals are a course you took, not yet a control you ran.
- A cybersecurity or information assurance degree carries it as work you can show: Security fundamentals are your coursework and your labs.
