排球计分程序(记分员)：
一，设计
估计这个任务需要多少时间 两星期
二，开发
1，需求分析---》拆成任务，编写代码 两星期
作为一名现场记分员，我希望详细记录比赛现场比分增长情况，
以便观众及运动员、教练员及时掌握比赛状况。（满意条件：
每一次比分的改变，都要形成一条记录）
任务：a，作为记分员需要知道每场比赛的比分，及增长情况；
b，观众及运动员、教练员及时掌握比赛状况；
2，生成设计文档 六天
由排球用户故事的需求可知，这个程序用来统计各个队伍的比分与比分增长情况，
3，设计复审 讨论，写文档
4，代码规范 根据vs2010进行规范
5，具体代码

6，代码复审 四小时
7，测试 修改代码，提交代码 四小时
三，报告：
1，测试报告：两小时
2，计算工作量：一小时
3，事后总结：里边还有不足，需要多加改进。
