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 Applicability
This International Standard has been demonstrated to apply to all functional domains. IFPUG continues to publish
white papers providing guidelines for use in evolving environments and domains.
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.
1.3 Audience
This International Standard can be applied by anyone requiring a measurement of functional size. Persons
experienced with the method will find this document to be a useful reference. In order to effectively apply this
International Standard, persons should be formally trained in the method using IFPUG Certified course materials. It
is also advisable to use this standard in conjunction with the other listed IFPUG publications.
