Software, like many other products, goes through a cycle of repeating phases. 译文：软件生命周期是软件工程中的一个基本概念。软件和许多其他产品一样，周期性地重复着一些阶段。 Modification is often needed due to errors found in the software, changes in the rules or laws, or changes in the company itself. The software should be modified before further use. 译文：由于软件中发现的错误、法规的变更或公司本身的变化，软件经常需要修改。在进一步使用之前，软件应该被修改。 software moves into the modification phase because errors are discovered; changes in the software application environment occur; user needs; the developer wants to improve the maintainability and reliability of the software for its further use. By “obsolete”, we mean the software loses its validity because of inefficiency, obsolescence of the language, major changes in the company, or other factors. 译文：“废弃”意味着，因效率低下、语言过时、公司重大变化或其他因素，软件失去了有效性。 The development process in the software li
