单项选择题 对于一个小型的软件开发项目，一个人就可以完成需求分析、设计、编码和测试工作。但随着软件项目规模的增大，需要有多人共同参与同一软件项目的工作。当几个人共同承担软件开发项目中的某一任务时，人与人之间必须通过交流来解决各自承担任务之间的(20)问题，即通信问题。通信需花费时间和代价，会引起软件错误(21)，(22)软件生产率。如果一个软件开发小组有n人，每两个人之间都需要通信，则共有(23)条通信路径。假设一个人单独开发软件，生产率是5000行/人年，且在每条通信路径上耗费的工作量是250行/人年。若4个人组成一个小组共同开发软件，则小组中每个人的软件生产率为(24)。若小组有6名成员，则小组中每个成员的软件生产率为(25)。因此，有人提出，软件开发小组的规模不能太大，人数不能太多，一般在(26)人左右为宜。
