Information technology — Object Management Group Automated Function Points (AFP), 1.0

1.1 Purpose This International Standard defines a method for automating the counting of Function Points that is generally consistent with the Function Point Counting Practices Manual, Release 4.3.1 (IFPUG CPM) produced by the International Function Point Users Group (IFPUG). Guidelines in this International Standard may differ from those in the IFPUG CPM at points where subjective judgments have to be replaced by the rules needed for automation. The IFPUG CPM was selected as the anchor for this International Standard because it is the most widely used functional measurement specification with a large supporting infrastructure maintained by a professional organization. 1.2 Applicability This International Standard is applicable to the functional sizing of transaction-oriented software applications, and in particular those with data persistency. To be consistent with the IFPUG CPM, the International Standard provides details on the support of applications using relational databases. However, the International Standard can be used and extended for any type of transactional application with data persistency. 1.3 Limitations This International Standard does not address the sizing of enhancements to an application or maintained functionality (often called Enhancement Function Points). Extensions of the automated counting methods described in this International Standard such as Automated Enhancement Function Points will be addressed in future addendums to this International Standard. This International Standard does not address sizing for the non-functional components of a software application. Non-functional components (as defined by IFPUG) include: — Structural Quality Constraints Reliability, Security, Performance Efficiency, Maintainability, etc. — Organizational Constraints locations for operations, target hardware, compliance to standards, etc. — Environmental Constraints interoperability, security, privacy, safety, etc. — Implementation Constraints development language, delivery schedule, etc.

Introduction
The rapid growth of distributed processing has led to a need for a coordinating framework for this
standardization and ITU-T Recommendations X.901-904 | ISO/IEC 10746, the Reference Model of Open
Distributed Processing (RM-ODP) provides such a framework. It defines an architecture within which
support of distribution, interoperability and portability can be integrated.
RM-ODP Part 2 (ISO/IEC 10746-2) defines the foundational concepts and modeling framework for
describing distributed systems. The scopes and objectives of the RM-ODP Part 2 and the UML, while
related, are not the same and, in a number of cases, the RM-ODP Part 2 and the UML specification use the
same term for concepts which are related but not identical (e.g., interface). Nevertheless, a specification
using the Part 2 modeling concepts can be expressed using UML with appropriate extensions (using
stereotypes, tags, and constraints).
RM-ODP Part 3 (ISO/IEC 10746-3) specifies a generic architecture of open distributed systems,
expressed using the foundational concepts and framework defined in Part 2. Given the relation between
UML as a modeling language and Part 3 of the RM-ODP standard, it is easy to show that UML is suitable
as a notation for the individual viewpoint specifications defined by the RM-ODP.
This International Standard defines a method for automating the counting of Function Points that is
generally consistent with the Function Point Counting Practices Manual, Release 4.3.1 (IFPUG CPM)
produced by the International Function Point Users Group (IFPUG). Guidelines in this specification may
differ from those in the IFPUG CPM at points where subjective judgments have to be replaced by the
rules needed for automation. The IFPUG CPM was selected as the anchor for this specification because
it is the most widely used functional measurement specification with a large supporting infrastructure
maintained by a professional organization.
