This part of ISO/IEC 14143 provides a summary of the FSM-related standards and the relationship between; a) the ISO/IEC 14143 series FSM framework International Standards that provide the definitions and concepts of FSM, and conformity and verification of FSMMs b) the ISO/IEC standard FSMMs, i.e. ISO/IEC 19761, ISO/IEC 20926, ISO/IEC 20968, ISO/IEC 24570 and ISO/IEC 29881 This part of ISO/IEC 14143 also provides a process to assist users to select and develop an FSMM that meets their requirements as well as providing guidance on how to use FS. FSMMs include, but are not limited to, ISO/IEC 19761, ISO/IEC 20926, ISO/IEC 20968, ISO/IEC 24570 and ISO/IEC 29881.

Note: An FSMM is a software sizing method that conforms to the mandatory requirements of ISO/IEC 14143-1. Recommending a specific FSMM is outside the scope of this part of ISO/IEC 14143. The audiences of this part of ISO/IEC 14143 are: users and potential users of FSM developers of an FSMM
