scope:

This part of ISO/IEC 14143 defines the fundamental concepts of Functional Size Measurement (FSM). This part of ISO/IEC 14143 does NOT provide detailed rules on how to:

⎯ measure Functional Size of software using a particular method;

⎯ use the results obtained from a particular method;

⎯ select a particular method.

This part of ISO/IEC 14143 is applicable when determining if a method for sizing software is an FSM Method. It does not prevent the development of various methods, but rather provides a basis for assessing whether a particular method conforms to FSM.

This part of ISO/IEC 14143 is intended for use by those persons associated with the acquisition, development, use, support, maintenance and audit of software.
