National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 14143-6 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and system engineering. ISO/IEC 14143 consists of the following parts, under the general title Information technology Software measurement Functional size measurement: Part 1: Definition of concepts Part 2: Conformity evaluation of software size measurement methods to ISO/IEC 14143-1:1998 Part 3: Verification of functional size measurement methods Technical Report Part 4: Reference model Technical Report Part 5: Determination of functional domains for use with functional size measurement Technical Report Part 6: Guide for use of ISO/IEC 14143 series and related International Standards Annex A of this part of ISO/IEC 14143 is for information only.

The first published method to embrace this concept was Function Point Analysis, developed by Allan J. Albrecht in the late 1970s. Since then, numerous extensions and variations of the original method have been developed. In the field of ISO/IEC International Standards, the following Functional Size Measurement-related International Standards and Technical Reports have been published: ISO/IEC 14143 series, parts 1 to 5, ISO/IEC 19761:2002, ISO/IEC 20926:2002, ISO/IEC 20968:2002, and ISO/IEC 24570:2004. This part of ISO/IEC 14143 was established to provide FSM Method users and developers with a guide as to how these International Standards and Technical Reports relate to each other and how to use them. The Functional Size (FS) obtained by measuring a piece of software contributes to a better understanding of the characteristics of the software, as well as the development, maintenance and support activities thereof. The three types of International Standards and Technical Reports related to the definition and use of FS and/or Functional Size Measurement (FSM) are: a) Concept Standards: Describe concepts and provide definitions; b) Supporting Standards: Supply information to assist in the evaluation of Functional Size Measurement Methods (FSMM) and examples of the software domains that they measure; and c) Method Standards: Define instances of FSMMs. Any FSMM, other than the Method Standards, can be used to measure FS as long as it conforms to ISO/IEC 14143-1. FSMMs can vary in their capability to measure software in different domains. Therefore, before deciding on which FSMM to use, it is advisable to assess the capability of the method to adequately size the software to be measured. This part of ISO/IEC 14143 provides guidance on how to select a suitable FSMM using all FSM-related International Standards. The FS results obtained from applying the selected FSMM can be used for a variety of purposes throughout the life cycle of the software. This part of ISO/IEC 14143 also provides illustrative examples of how to use FSM and functional size to manage aspects of software development and maintenance.

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 provides guidance on how to use FS. This part of ISO/IEC 14143 also gives guidance on how to use FS. FSMMs include, but are not limited to, ISO/IEC 19761, ISO/IEC 20926, ISO/IEC 20968 and ISO/IEC 24570. 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; and developers of an FSMM. 2 Abbreviated terms BFC Base Functional Component FS Functional Size FSM Functional Size Measurement FSMM Functional Size Measurement Method FUR Functional User Requirement Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Hong Kong Polytechnic Univ/9976803100 Not for Resale, 04/17/2007 09:57:23 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO/IEC 14143-6:2006(E) 2 © ISO/IEC 2006 All rights reserved 3 FSM related standards (ISO/IEC 14143 series), FSMM standards, and their interrelationships 3.1 Outlines of FSM related standards 3.1.1 Overview Function Point Analysis was established in the late 1970s. It has subsequently been used worldwide. Over time alternative methods have been derived and devised. Although these methods vary in the rules they use to measure software, they all focus on measuring FURs of software. ISO/IEC 14143-1 defines concepts of FSM and FSMM. Subsequent parts of ISO/IEC 14143 (ISO/IEC 14143 series) have been developed to evaluate FSMMs. The following clauses outline these FSM related standards. NOTE For copies of the Scope clauses of the FSM related standards, refer to Annex A of this part of ISO/IEC 14143. 3.1.2 ISO/IEC 14143-1 ISO/IEC 14143-1 is a Concept Standard and is a basis for other International Standards and Technical Reports that are categorized as Supporting Standards and Method Standards. This part of ISO/IEC 14143 is the foundation standard of the series and has the following contents: a) Definitions b) Characteristics of FSMMs c) Requirements for FSMMs d) Process for applying an FSMM e) FSMM labelling conventions ISO/IEC 14143-1 is an International Standard. 3.1.3 ISO/IEC 14143-2 ISO/IEC 14143-2 is a Supporting Standard. This part of ISO/IEC 14143 defines processes to check conformity of a Candidate FSMM with ISO/IEC 14143-1. Using ISO/IEC 14143-2 is recommended whilst the conformity assessment can be done without using ISO/IEC 14143-2. ISO/IEC 14143-2 has the following contents: a) Evaluator characteristics b) Inputs to conformity evaluation c) Tasks and steps of the conformity evaluation procedure d) Conformity evaluation outputs e) Conformity evaluation result Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Hong Kong Polytechnic Univ/9976803100 Not for Resale, 04/17/2007 09:57:23 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO/IEC 14143-6:2006(E) © ISO/IEC 2006 All rights reserved 3 In addition, there are the following annexes: a) Evaluator capability (Informative) b) Example of a conformity evaluation checklist (Informative) c) Example of a conformity evaluation report (Informative) ISO/IEC 14143-2 is an International Standard. 3.1.4 ISO/IEC TR 14143-3 ISO/IEC TR 14143-3 is a Supporting Standard.
