Introduction
In order to effectively support the landing and implementation of GB/T 18491 "Information Technology Software Measurement Function Scale Measurement", define a
The functional size measurement method of GB/T 18491 is formulated in this document.
Since the mid-1970s, the method of measuring the functional size of software in function points has grown from a few interest groups to
For an impressive global organization. Alan Albrecht was the first to publicly publish a measure of software size
People, this method is called the function point counting method. With the increase of the use of function points, the application and use of this method are becoming more and more extensive. since
Albrecht's software function classification method. The functional size measurement methodology defined in this document facilitates a consistent solution to functional size measurements.
release. The measurement method of the IFPUG functional scale is also called the function point counting method, and the unit of its functional scale is called the function point.
Organizations can apply this document to measure the size of software products for.
--- Support quality and productivity analysis;
--- Estimate the cost and resources required for software development, enhancement and maintenance;
--- Provide a normalization factor for software comparison;
--- Determine the size of the purchased application package by grading all the functions contained in the application package;
--- Help users determine the benefits of an application package to their organization by determining the functional size specific to their needs.
Function point analysis measures software by quantifying the tasks and services (i.e., functions) it provides to users based primarily on its logical design. Function
The purpose of point analysis is to measure.
--- Functions requested and received by users implemented in the software;
--- Does not depend on the implementation of its technology to measure the scale of software development and maintenance.
The process of function point analysis is.
--- Simple enough to minimize the cost of the measurement process;
---Measurements are consistent across projects and organizations.

1 Scope
1.1 Purpose
This document specifies the definitions, rules and procedures for the IFPUG Functional Size Measurement (FSM) method.
1.2 Consistency
This document follows the provisions in ISO /IEC 14143-1.2007.
1.3 Applicability
This document applies to all functional areas.
Note. The IFPUG organization continues to publish white papers to provide guidance for evolving environments and fields.
This document is fully compatible with previous versions of the IFPUG scale measurement method.
IFPUG function point analysts have identified different delivery rates (time to deliver a single function point) that differ from those in
related to applications built in functional areas calibrated for different project sizes and software complexities.
1.4 Users
This document is intended for any user who needs to measure the size of a function. For experienced users, this document provides a useful reference.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Adaptive maintenance adaptive maintenance
The modification of a delivered software product to adapt to a changed or changing environment.
Note. Adaptive maintenance provides the necessary improvements to adapt to changes in the environment in which the software product must run. In order to keep up with the changing environment
Synchronization should make the corresponding changes. For example, the operating system may be upgraded and certain changes may be made to accommodate the new operating system.
