The Absence of Accessibility in Software Sizing Frameworks: A Gap Analysis of UCP, COSMIC, and IFPUG SNAP
Secure and Accessible Software Systems: 47SE 2026
Accurate software cost estimation depends on sizing methods that capture the full scope of project requirements, including non-functional requirements such as accessibility. This study examines whether three established sizing frameworks, Use Case Points (UCP), COSMIC Function Points, and IFPUG SNAP, operationalise accessibility as a non-functional…
