SecondMark position
An opinion has a validity envelope. Continuous assurance monitors the evidence and change events that can move a system outside it.
The examination is bounded to defined claims, a versioned system, and evidence that can be traced to the state under review. Any material exclusion or uncertainty remains visible in the conclusion.
Core questions
What the examination needs to establish.
- 01
Which changes can invalidate the opinion?
- 02
Can material drift be detected and attributed?
- 03
Are production incidents reflected in the evidence model?
- 04
When must a claim be re-examined?
Evidence model
Evidence is assembled around the claim—not the folder structure.
Architecture and system boundaries
Collected, attributed, challenged, and connected to the exact system boundary under examination.
Implementation and model provenance
Collected, attributed, challenged, and connected to the exact system boundary under examination.
Runtime behavior and operational history
Collected, attributed, challenged, and connected to the exact system boundary under examination.
Controls, qualifications, and unresolved risk
Collected, attributed, challenged, and connected to the exact system boundary under examination.
Intended outcome
A controlled assurance cadence tied to material change, not a permanent badge detached from the evolving system.
Professional boundary
What an opinion does—and does not—mean.
It provides
A traceable independent conclusion on defined claims, grounded in the evidence and system state examined.
It does not provide
A guarantee that failure is impossible, a permanent certification, or a conclusion beyond the stated scope and validity conditions.
