Scope

This standard specifies a set of definitions, rules, and steps for applying a non-functional size measurement method and provides guideline and examples of how to use the size measurements in software projects

Purpose

ISO/IEC/IEEE 32430 defines a method for measuring the non-functional size of the software. Having both the functional size and the non-functional size provides a complete view of users’ requirements.

The work effort to deliver all user requirements result from these two sizes. Hence, measuring the nonfunctional size improves the accuracy of cost estimation. In addition, Key Performance Indicators (KPIs), such as productivity, are calculated more accurately when considering both sizes and the effort to meet all requirements, functional and non-functional.

The standard shows complementary to ISO/IEC 20926:2009 “Software and systems engineering — Software measurement — IFPUG functional size measurement method”.

This project is a revision of ISO/IEC/IEEE 32430:2021 Software engineering — Trial use standard for software non-functional sizing measurements. The revision will apply technical and editorial clarifications and corrections based on users' experience and improvements made by ISO and IEEE Working groups.
