<DIV align=left>2.3详细调查</DIV>
<DIV align=left>新系统是在现有系统的基础上发展起来的。为了使新系统比现有系统工作的更加经济有效，必须首先做好对现有系统的详细调查。</DIV>
<DIV align=left>1.详细调查的目标和内容</DIV>
<DIV
align=left>在可行性研究的基础上进一步对现行全面、深入的调查和分析，弄清楚现行系统运行状况，发现其薄弱环节，找出要解决的问题实质，确保新系统更有效。</DIV>
<DIV align=left>详细调查的主要内容包括对现行系统的目标、主要功能、数据流程的调查和分析。</DIV>
<DIV align=left>2.详细调查的方法</DIV>
<DIV align=left>
为了确保调查工作顺利进行，系统分析人员要注意工作方法和工作手段。切实与用户建立良好的关系，让用户充分地、积极地参与调查工作。</DIV>
<DIV align=left>
具体方法有直接面谈或专门访问，发调查表征求意见，召开讨论会，阅读历史资料和参加业务实践，其中参加业务实践，与具体工作人员一起完成最基本的工作程序是最有效的方法。</DIV>
<DIV align=left>2.4管理业务的调查</DIV>
<DIV align=left>2.4.1 组织机构和职责的调查</DIV>
<DIV align=left>了解清楚对象系统内部各种组织机构可以向系统分析人员进一步明确调查对象和方向。调查结果可以用组织结构</DIV>
<DIV align=left> </DIV>
<DIV align=left>2.4.2管理业务流程分析</DIV>
<DIV
align=left>业务流程图体现了信息的流动过程，顾客和业务员签订合同书后，由业务员交于外联主管统一管理，外联主管做好合同档案，让财务部作费用预算，如发现无利润时向外联主管发放不合格预算单，再由外联主管向客户发出取消合同通知书，如项目有一定利润则有外联主管向策划人员发放编写策划书通知单，向演艺人员发出节目通知单如演员在这个时间段可以演出则向公司发出节目执行单，再将编写好的策划书交由该项目负责人，在向工程部发放施工单，项目扶责任和工程部一起监督项目的实施过程。</DIV>
<DIV align=left>系统的业务流程图如下：（图2-2）</DIV>

<DIV align=left> 图2-2</DIV>

<DIV align=left>2.5数据流程的分析</DIV>
<DIV
align=left>数据流程图描述系统的逻辑模型，图中没有任何具体的物理元素，只是描述信息在系统中流动和处理的情况。设计数据流程图只需考虑系统必须完成的基本逻辑功能，而不需考虑如何具体的实现这些功能。</DIV>
<DIV align=left>1. 确定系统界面。</DIV>
<DIV align=left>2. 自顶向下、逐层分解。</DIV>
<DIV align=left>3. 合理布局。</DIV>
<DIV align=left>4. 数据流程图只反映数据流向、数据加工和逻辑意义上的数据存储。</DIV>
<DIV align=left>5. 数据流程图绘制过程就是系统的逻辑模型的形成过程，必须始终和用户密切接触。</DIV>
<DIV align=left>在仔细调查企业信息管理过程的基础上，得到本系统所处理的数据流程图如下图所示：</DIV>
