Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. 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

Introduction
Functional Size Measurement (FSM) is a technique used to measure the size of software by quantifying the
1)
Functional User Requirements of the software . The first published method to embrace this concept was
Function Point Analysis, developed by Allan Albrecht in the late 1970s. Since then, numerous extensions and
variations of the original method have been developed. The end user may have many variants from which to
choose, each with its own advantages in specific situations. ISO/IEC 14143-1 was developed to define the
concepts of FSM and provides a basis against which the user can compare all variants. This part of
ISO/IEC 14143 was developed to provide a process for checking whether a Candidate FSM Method conforms
to the provisions of ISO/IEC 14143-1. The output from this process can assist prospective users of the
Candidate FSM Method in judging whether it is appropriate to their needs.

1 Scope
This part of ISO/IEC 14143:
a) establishes a framework for the conformity evaluation of a Candidate FSM Method against the provisions
of ISO/IEC 14143-1;
b) describes a process for conformity evaluation of whether a Candidate FSM Method meets the (type)
requirements of ISO/IEC 14143-1 such that it is an actual FSM method, i.e. they are of the same type;
c) describes the requirements for performing a conformity evaluation in order to ensure repeatability of the
conformity evaluation process, as well as consistency of decisions on conformity and the final result;
d) aims to ensure that the output from the conformity evaluation process is objective, impartial, consistent,
repeatable, complete and auditable;
e) provides informative guidelines for determining the competence of the conformity evaluation teams;
f) provides an example checklist to assist in the conformity evaluation of a Candidate FSM Method; and
g) provides an example template for the conformity evaluation report.
