ISO/IEC 19761:2011 specifies the set of definitions, conventions and activities of the COSMIC Functional Size Measurement Method. It is applicable to software from the following functional domains:
application software;
real-time software;
hybrids of the above.
ISO/IEC 19761:2011 has not been designed for measuring the functional size of a piece of software, or its parts, which
is characterized by complex mathematical algorithms or other specialized and complex rules, such as can be found in expert systems, simulation software, self-learning software and weather forecasting systems, or
processes continuous variables such as audio sounds or video images, such as can be found in computer game software, musical instruments and the like.
