IEEE 15026-2-2011

15026-2-2011 is a systems and software engineering standard focused on systems and software assurance, with particular attention to the assurance case. In the context of computing and processing, it helps organize evidence and arguments used to show that a system is acceptably safe or reliable for its intended use. This makes 15026-2-2011 useful for teams that need a structured way to support assurance claims during development, review, and verification.

Overview of 15026-2-2011

This technical document addresses assurance case practice within systems and software assurance. It is intended to support clear reasoning about why a system can be trusted, based on stated claims, supporting evidence, and the logical links between them. For organizations working with complex software-intensive systems, 15026-2-2011 can help define a more disciplined basis for assurance activities, especially where safety, dependability, or stakeholder confidence must be demonstrated.

Typical use cases

15026-2-2011 is commonly relevant when documenting assurance arguments for embedded control systems, industrial automation platforms, transport-related software, or other computing systems where evidence must be presented in a structured form. It may also be used in design reviews, verification planning, and compliance-oriented documentation. Teams can apply it when building an assurance case for a specific system function, subsystem, or operational claim, especially when multiple sources of evidence need to be traced and assessed.

Why it matters

In practice, 15026-2-2011 helps reduce ambiguity in how assurance is argued and reviewed. A well-structured assurance case can improve consistency across engineering, testing, and approval activities, making it easier to see whether the available evidence supports the required claims. For procurement, certification support, or internal governance, this standard can improve confidence in decision-making and help identify gaps in the assurance package before release or deployment.
