IEEE P15026-2

P15026-2 is the English-language standard for Part 2: Assurance case, focusing on computing and processing contexts where a structured argument and supporting evidence are needed to justify a claim. It is relevant when organizations need a clear way to present confidence in a system, process, or component and to show how that confidence has been built. As an inactive technical document, P15026-2 is mainly useful for reference, comparison, or legacy compliance work.

About P15026-2

P15026-2 addresses the assurance case aspect of the broader P15026 standard family, which suggests a formal approach to arguing that a system or process meets defined expectations. In computing and processing applications, an assurance case typically links claims, reasoning, and evidence in a traceable structure. This standard can therefore support technical review, documentation discipline, and consistency when evaluating whether a solution has been adequately justified. For organizations working with established requirements, P15026-2 offers a focused reference point.

Where is P15026-2 used?

P15026-2 is most relevant in environments where computing or processing systems require documented assurance rather than simple functional description. That can include engineered software systems, control or processing workflows, and technical submissions that must demonstrate a defensible case for trust, dependability, or compliance. It is especially useful when teams need to align design decisions, analysis results, and evidence into one coherent technical argument. In practice, P15026-2 may support internal review, supplier assessment, or archived documentation.

Importance in practice

In practice, the value of P15026-2 lies in helping teams organize assurance evidence in a consistent and reviewable form. That reduces ambiguity during design checks, audits, procurement reviews, and acceptance activities. A clear assurance case can make it easier to identify gaps, compare alternatives, and defend technical decisions with traceable support. For inactive standards work, it can also help preserve a common reference when maintaining older systems or evaluating documentation against legacy expectations.
