Introduction

Functional Size Measurement (FSM) is a technique to measure the size of software by quantifying the functional requirements of software users. Originally published package the method of containing this concept is analyzed by the AlanAlbercht in the 1970s, developed in the late function points. Thereafter, the original method We developed a number of extensions and variants. In ISO/IEC international standards in the field, and functional size measurement related to the following international standards and technical reports Report has been published.

ISO/IEC 14143 series of standards, Part 1 to Part 5 (corresponding to GB/T 18491.1 ~ 18491.5);

--- ISO/IEC 19761:2002;

--- ISO/IEC 20926:2002;

--- ISO/IEC 20968:2002;

--- ISO/IEC 24570:2004.

The purpose of this part of the preparation of these standards is to provide for users and developers FSM approach and guide the relationship between use.

Function scale (FS) by measuring embodied in a software, the software will help to better understand the characteristics of its development, maintenance and support Support activities. Size and function and (or) the definition and use of functional size measurement standards related to three types.

a) the concept of standards. describe concepts and provide definitions;

b) support standards. to provide accessibility size measurement method (FSMM) evaluation of information, and provide examples of software field measurements;

c) the standard method. Examples of definitions FSMM.

In addition to the standard method, provided that they meet GB/T 18491.1, can be used to measure any FSMM FS. FSMM measurement software can Force fields can vary vary. Therefore, before deciding which FSMM, to properly assess the scale of the tested software fix Capability approach is wise.

This section provides the use of all standard and functional size measurement related to the selection of suitable FSMM guide.

Features a variety of purposes scale application selected FSMM results obtained can be used throughout the software life cycle. This section also provides for how to use the FSM and function to manage the size of an illustrative example of software development and maintenance.

1 Scope

This section GB/T 18491 provides a functional size measurement between (FSM) standards general description and the following criteria relationship.

--- GB/T 18491 series FSM framework of standards that provide FSM definitions and concepts as well as functional size measurement Party Law (FSMM) compliance and verification;

--- ISO/IEC FSMM standard, ISO/IEC 19761, ISO/IEC 20926, ISO/IEC 20968 and ISO/IEC 24570.

This section also provides help in the selection and development process to meet their needs FSMM and how to use the function scale (FS) of guide. FSMM including but not limited to ISO/IEC 19761, ISO/IEC 20926, ISO/IEC 20968 and ISO/IEC 24570 four standard.

NOTE. FSMM software size measurement method is in line with GB/T 18491.1 mandatory requirements, recommended specific FSMM beyond the scope of this section.

Expected readership of this section is.

--- FSM users and potential users;

--- FSMM the developer.
