IEEE P15026-2/CD, Feb 2020

P15026-2/CD, Feb 2020 is a technical document for computing and processing that focuses on Part 2: Assurance case. It is relevant where a structured argument and supporting evidence are needed to show that a system, process, or component meets defined confidence targets. As a draft committee document, P15026-2/CD, Feb 2020 is useful for teams assessing compliance, managing risk, and documenting assurance in software-intensive and information-processing environments.

What is P15026-2/CD, Feb 2020?

P15026-2/CD, Feb 2020 sets out the Part 2 requirements and guidance for building an assurance case. In practical terms, an assurance case organizes claims, evidence, and reasoning so stakeholders can evaluate whether a computing or processing solution is sufficiently dependable for its intended use. The standard is especially relevant when formal justification is needed rather than simple testing alone, helping align design intent with documented evidence and reviewable arguments.

Where is P15026-2/CD, Feb 2020 used?

P15026-2/CD, Feb 2020 is commonly used in development and verification work for software-based systems, digital control platforms, and other computing environments where trustworthiness must be demonstrated. It may support engineering teams, assessors, and procurement groups that need a clear assurance case for critical functions, system integration, or acceptance reviews. The document is also relevant when evidence must be presented in a way that is traceable and easy to audit across the lifecycle.

Why is P15026-2/CD, Feb 2020 important?

This standard matters because assurance cases help reduce ambiguity in how confidence is justified. P15026-2/CD, Feb 2020 can support better design control, clearer compliance discussions, and more consistent evaluation of evidence during testing and review. For complex computing and processing applications, a structured assurance approach may help identify gaps earlier, improve accountability, and make technical claims easier to defend during procurement, approval, or safety-related assessment activities.
