ISO/IEC 20926
ISO/IEC 20926 is an international standard that defines the IFPUG (International Function Point Users Group) method for measuring the functional size of software. It provides a standardized approach to quantify the functionality delivered to users by software applications, based on user requirements and logical design. This measurement is used for estimating effort, tracking productivity, and managing software projects.
Developers should learn ISO/IEC 20926 when involved in software project management, cost estimation, or quality assurance, as it helps in objectively sizing software for better planning and resource allocation. It is particularly useful in industries requiring compliance with standardized metrics, such as government contracts or large-scale enterprise projects, to ensure consistency and comparability across different software developments.
