/>需求开发与管理是软件项目中一项十分重要的工作，据调查显示在众多失败的软件项目中，由于需求原因导致的约占到45%，因此，需求工作将对软件项目能否最终实现产生至关重要的影响。虽然如此，在项目开发工作中，很多人对需求的认识还远远不够，从本人参与或接触到的一些项目来看，小到几十万元，大到上亿元的软件项目的需求都或多多少的存在问题，有的是开发者本身不重视原因、有的是技术原因、有的是人员组织原因、有的是沟通原因、有的是机制原因，以上种种原因都表明做好软件需求开发是一项系统工作，而不是简单的技术工作，只有系统的了解和掌握需求的基本概念、方法、手段、评估标准、风险等相关知识，并在实践中加以应用，才能真正做好需求的开发和管理工作。 <br />本文将通过介绍关于软件需求的基本知识和个人在实际工作中总结的一些经验，帮助读者了解软件需求，学习需求开发的一些基本方法，避免因需求原因而导致的项目失败。 <br />1 什么是软件需求和需求工程 <img src ="http://blog.csdn.net/xieqibao/aggbug/2738070.aspx" width = "1" height = "1" />Wed, 30
