 Other software sizing methods include Use Case-based software sizing, which relies on counting the number and characteristics of use cases found in a piece of software, and COSMIC functional size measurement, which addresses sizing software that has a very limited amount of stored data such as 'process control' and 'real time' systems.Both the IFPUG Method and the COSMIC Methods are ISO/IEC standards.The IFPUG method to size the non-functional aspects of a software or component is called SNAP, therefore the non-functional size is measured by SNAP Points.
