随着信息技术的发展，传统的软件开发方法已经不能适应用户不断变化的需求，大量的软件开发企业需要一种灵活的、能够基于一套产品代码进行扩展的软件开发方法来满足用户的需求，以达到用最少的人力资源争取最大的市场份额。本文比较了目前主流的几种软件扩展开发方法，分析了各种开发方法的优缺点，并提出了一种新的软件开发方法——插件化软件开发方法；给出了插件化开发方法的定义和使用方法，同时分析了此方法的优缺点，并提出了建议的使用场景。

With the development of information technology, the traditional software development methods cannot adapt to the requirement of users. In order to use the minimum resources to gain the maximum market share, a large number of software development companies need a flexible architecture to extend software functions based on a set of codes. This paper compares the current software extension methods, analyzes their advantages and disadvantages, and proposes a new software extension method—plug-in development method. It gives the definition and usage of plug-in development method. At the same time, the advantages and disadvantages of this method are analyzed, and the proposed usage scene is put forward.
