Preface:

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

This Standard supersedes CAN/CSA-ISO/IEC 20926-04 (adoption of ISO/IEC 20926:2003, first edition, 2003-10-01). At the time of publication, ISO/IEC 20926:2009 is available from ISO and IEC in English only.

Scope:

1.1 Purpose
This International Standard specifies the set of definitions, rules and steps for applying the IFPUG functional size measurement (FSM) method.

1.2 Conformity
This International Standard is conformant with all mandatory provisions of ISO/IEC 14143-1:2007.

1.3 Applicability
This International Standard can be applied to all functional domains.

NOTE IFPUG continues to publish white papers providing guidelines for use in evolving environments and domains.

This International Standard is fully convertible to prior editions of IFPUG sizing methods.

IFPUG function point analysts have identified different delivery rates (hours to deliver a function point) related to building applications in different functional domains calibrated for varying project sizes and software complexities.

1.4 Audience
This International Standard can be applied by anyone requiring a measurement of functional size. Persons experienced with the method will find this International Standard to be a useful reference.
