问题 So it is today.Schedule disaster,functional misfits,and system bugs all arise because the left hand doesn’t know what the right hand is doing.As work（　　）,the several teams slowly change the functions,sizes,and speeds of their own programs,and they explicitly or implicitly（　　）their assumptions about the inputs available and the uses to be made of the outputs.For example,the implementer of a program-overlaying function may run into problems and reduce speed relying on statistics that show how（　　）this function will arise in application programs.Meanwhile,back at the ranch,his neighbor may be designing a major part of the supervisor so that it critically depends upon the speed of this function.This change in speed itself becomes a major specification change,and it needs to be proclaimed abroad and weighed from a system point of view.How,then,shall teams（　　）with one another?In as many ways as possible：Informally.Good telephone services and a clear definition of intergroup dependencies will encourage the hundreds of calls upon which common interpretation of written documents depends.Meetings.Regular project meetings,with one team after another giving technical briefings,are（　　）.Hundreds of minor misunderstandings get smoked out this way.Workbook.A formal project workbook must be started at the beginning.问题1选项A.startsB.proceedsC.stopsD.speeds问题2选项A.changeB.proceedC.smoothD.hide问题3选项A.frequentlyB.usuallyC.commonlyD.rarely问题4选项A.workB.programC.communicateD.talk问题5选项A.worthlessB.valuelessC.uselessD.invaluable
选项
答案 BADCD
解析 今天也是如此，进度灾难，功能不称职，和系统Bugs的出现，都是因为左手不知道右手正在做什么。随着工作的开展，几个团队慢慢修改他们程序的功能，大小，都有各自的速度，并显式或隐式改变了他们假定的输入和使用的输出。
例如，一个程序覆盖函数的实现者可能会遇到问题，和减慢速度，这依赖于在应用程序中使用该函数的功能多少的统计情况。与此同时，回到现场，他的邻居可能是设计一个主要部分的主管，它的速度主要取决于该功能。这种变化在速度本身成为一个主要规格变化，它需要宣布，并从一个系统的角度来衡量。
然而，团队之间应该如何进行沟通呢？有如下几种方式：
非正式的方式：良好的电话服务和明确定义团体之间的依赖关系，将鼓励数以百计的呼叫，这取决于预先编写的文档。
会议：定期的项目会议，一个接一个的团队技术简报是无价的，数百的小误解可以被解除。
工作手册：一个正式的工作手册必须在开始时被制定。
