A task team to improve project needs analysis summary
a. analyze the content of "XX project requirements specifications" insufficient draft, in particular the requirement description modeling incomplete.
- Just spent the questionnaire acquisition analysis
- Requirements specification is not standardized layout
- The school leaders can not see into the attendance list
- Special holiday traffic situation during the great Ben collapse of the system is not considered
- Preliminary information on students without taking into account security
Perfect team project requirements specification

团队项目系统设计
系统设计过程：首先通过原型设计以及需求的二次分析，进一步更新了《需求规格说明书》，然后通过学习软件系统总体结构和数据库逻辑结构设计，编制了《软件系统设计说明书》，再通过各成员的分工进行下一步的工作。
设计方法：面向对象的分析和设计方法
建模工具：Visio

团队项目系统设计过程总结
- 开发小组的人员应少而精，开发人员的素质和数量是影响软件质量和开发效率的重要因素，不需要打酱油者 应该少而精。小组的成员虽然做了不同的分工，但最终所有的项目都需要做整合，团队合作精神很重要。
- 在开发设计实行严格的产品控制，最痛恨的事情之一莫过于改动需求。但是实践告诉我们，需求的改动往往是不可避免的。这就要求我们要采用可续的产品控制技术来顺应这种要求。也就是要采用变动控制。当需求变动时，其他各个阶段的文档或代码也随之变动，以保证软件的一致性。
- 软件系统的设计是一个复杂的过程，虽然我们运用了现今较为流行的面向对象的分析和设计方法，但是有些制图和建模过程中，设计还是十分繁琐的，此时，我们就要做到有耐心，不浮躁，静下心来认真的完成设计。
