Evidence note

ISO/IEC/IEEE 15026-2:2022 - Assurance Case

Technical Standard2022ISO / IEC / IEEE

What does it cover?

A standard specifying requirements for the structure and terminology of assurance cases.

Key points

  1. 1Assurance cases provide a structured way of connecting technical claims, arguments, evidence and assumptions.
  2. 2Assurance reasoning can be applied to properties including reliability, maintainability, operability and security.

Why it matters. Lornets interpretation.

Lornets' Claim, Evidence, Verification and Conclusion structure draws on the same broader assurance tradition: important technical claims should be supported by explicit evidence and bounded assumptions.

This is the Lornets reading of the source, not a finding of the source itself.

What it does not establish

  1. 1Lornets should not claim ISO/IEC/IEEE 15026-2 conformity unless a specific engagement actually implements the standard's requirements.
  2. 2The standard does not validate the Lornets methodology.
  3. 3Lornets uses it as an external assurance reference.
