Definition
Operational risk assessment identifies and models the vulnerabilities of, and risks to, an organization's activities individually and as a whole.
Implementation perspective
Operational Risk Assessment should be treated as a technical defensive capability rather than a product checkbox. In practice, teams should define the protected scope, the conditions under which the technique acts, and the observable evidence that demonstrates the intended behavior. For this technique, likely engineering context includes the relevant system, activity, and evidence sources.
Use the technique to improve the shared model of systems, activities, dependencies, threats, or risk before making defensive decisions.
Questions to ask
- What system, activity, relationship, or risk is being modeled, and where is the scope boundary?
- Which authoritative data sources populate the model, and how is their quality assessed?
- How often is the model refreshed after architectural, operational, or threat changes?
- Which decisions, analyses, or engineering actions are expected to use the model?
Evidence and validation
- Documented model scope, assumptions, and ownership
- Source inventories, data-quality checks, and refresh records
- Version history showing material changes to the model
- Examples of decisions or analyses that used the model
Common failure patterns
- The model is treated as a one-time diagram rather than a maintained decision aid.
- Unverified or stale source data is accepted without recording uncertainty.
- The model is comprehensive in appearance but disconnected from engineering or operational decisions.
