软件功能规模度量方法中的软件分层问题分析

Analysis of Problem in the Functional Size Measurement Method of Layered Software

自从AllanAlbrecht在1979年提出功能点分析(FPA)思想之后,功能规模度量(FSM)方法在之后的40年中经历了20世纪80年代末的高潮和20世纪90年代末的低谷.在那之后人们对FSM采取了更加科学和实用化的态度,并在软件项目管理的各个阶段、软件应用的各个领域、软件设计的各种体系结构中进行探索和深入研究.本文就软件功能分析过程中形成的软件分层问题进行探讨,分析COSMICFFP给出的基准案例,给出了基于需求规格说明的功能规模度量规则,从而减少了功能规模度量的重复计数.

Since Allan Albrecht came up with Function Point Analysis(FPA), Functional Size Measurement(FSM), during the next 40 years, experienced the peak in the late 1980s and the trough in the late 1990s, after which researchers began to regard FSM as more scientific and practical and had a deeper exploration in each step of software project management, each field of software application, and each kind of structure of software design. The article discusses the layered software problem in analyzing software function, analyzes the benchmark case from COSMIC FFP, and provides the rules in Functional Size Measurement Method based on requirement specification, which reduces the repeat count in Functional Size Measurement.
