ISO/IEC 14143-1:2007/COR1:2011 is a technical corrigendum to the functional size measurement framework defined in Information technology - Software measurement - Functional size measurement - Part 1: Definition of concepts - Technical Corrigendum 1. It serves as a supporting correction to the parent document, helping organizations rely on a more accurate and consistent measurement reference. For teams using ISO/IEC 14143-1:2007/COR1:2011 in engineering documentation, procurement review, or verification activities, the corrigendum can be important where precise terminology and aligned concepts affect documented evaluation and technical assessment.

Overview of ISO/IEC 14143-1:2007/COR1:2011

This corrigendum is connected to the ISO/IEC 14143 series and should be read as a modifying reference rather than a standalone functional size measurement specification. Its role is to correct or refine the concepts used in the parent part, which supports consistent interpretation of software measurement practices. In compliance workflows, that kind of update may be relevant when organizations are preparing internal methods, reviewing measurement evidence, or maintaining engineering documentation that depends on stable and traceable definitions.

Compliance applications of ISO/IEC 14143-1:2007/COR1:2011

Organizations may use ISO/IEC 14143-1:2007/COR1:2011 when aligning software size measurement procedures across development, verification, and quality workflows. It can support technical review of measurement rules, documented evaluation of functional sizing methods, and procurement discussions where comparable metrics are needed for supplier deliverables. In laboratories, audit preparations, or software governance processes, the corrigendum may help ensure that assessment records and conformity assessment evidence are based on the corrected parent reference.

Importance of compliance with ISO/IEC 14143-1:2007/COR1:2011

Compliance with the corrected reference helps reduce ambiguity in functional size measurement, which can improve consistency across teams and projects. That matters for operational consistency, engineering validation, and risk management when measurement results are used in planning, acceptance checks, or performance tracking. A clear and corrected technical reference also supports procurement comparisons and conformity assessment preparation by making documented criteria easier to review, verify, and justify during audits or technical approvals.

• Technical corrigendum to the parent software measurement concepts document
• Supports more consistent interpretation of functional size measurement terminology
• Useful for documented evaluation, technical review, and verification activities
• Can assist quality assurance, procurement review, and compliance workflows
