解析 分析阶段回答谁将使用该系统、系统能做什么及系统在何时何地使用的问题。在该阶段，项目组调研当前系统、识别改进机会并开发出一个新系统的概念。这个阶段分为三个步骤：首先，开发一个分析策略来指导项目组工作。这些分析策略通常包括了当前系统及其问题的分析和设计新系统的方法。下一步是需求收集。对这些信息（汇同系统发起人和很多其他人员的输入）的分析会导致开发出一个新系统的概念。系统概念作为开发一组业务分析模型的基础，这些模型描述了新系统开发完成后企业如何运作。这组模型通常包含那些表示数据和过程的模型，这些数据和过程是支持底层业务过程所必需的。最后，这些分析、系统概念和模型合并到一个称为系统建议书的文档中，将被提交给项目组发起人和其他决定项目是否继续执行的主要决策人员。
