问题 单项选择题

大型信息技术项目一般在需求不十分清晰的情况下开始,项目分成两个主要阶段:需求定义阶段和需求实现阶段。关于大型信息技术项目的需求管理,______的说法是正确的。

A.为了计划的严肃性,项目计划在需求定义完成时,不能进行大的修订
B.项目需求定义和需求实现通常是由不同的组织完成的
C.项目需求定义和需求实现一般是由一方完成的
D.项目WBS可以按照组织结构、可交付物、基准计划三个层面进行分解

答案

参考答案:B

解析: 通常,大型信息技术项目需求定义阶段要求对业务领域有深刻的理解,需求实现阶段则主要放在对技术领域的精通上,即这两个阶段要求完成的任务性质并不一致,很难将这两部分的能力同时体现在一个组织机构上。
由于项目具有渐进明细的特性,项目需求将随着项目的进展而逐步清晰,会导致项目的实际状况和计划差异较大。因此项目计划在需求定义完成时,还应该进行一次较大的修订。
在制订大型项目范围管理计划时,可以按照项目的组织结构、产品结构和生命周期3个角度制订分解结构。

When it comes to protecting the privacy of their children, U.S. parents give social networks a failing grade. According to a recent survey, three out of four parents believe social networks are not doing a good job of protecting kids’ online privacy.

The survey was conducted for Common Sense Media, a nonprofit organization devoted to helping families find the right way to deal withthe world of media and technology.

Ninety-two percent of parents said they are concerned that children share too much information online, and 85 percent said they are more concerned about online privacy than they were five years ago. In other findings, Common Sense Media found that 68% of parents are not at all confident in search engines keeping their private information safe and secure and 71% of parents said the same about social networking sites.

The survey found a great deal of concern about the online geo-location services which find and show the exact position of somebody through the net. Ninety-one percent of parents said search engines and social networking sites should not be able to share the physical location of children with other companies unless the parents approve.

“The survey results present a clear divide between the industry’s view of privacy and the opinion of parents and kids,” Common Sense Media CEO and founder James Steyer said.

“American families are deeply worried about how their personal information is being used by technology and online companies, yet the companies appear to be keeping their heads deep in the sand,” Steyer said.

IT companies need to step up but parents, children, schools and government also need to do more, he said.

“Parents and kids have to educate themselves about how to protect their information,” he said. “Schools should teach all students and their parents about privacy protection.”

“And finally, policymakers have to update privacy policies for the 21st century,” he said. According to the survey, more than 60 percent of parents want the US Congress to update online privacy laws for children and teenagers.
