[说明]
软件资源就是指企业整个环境中运行的软件和文档,其中程序包括操作系统、中间件、市场上买来的应用、本公司开发的应用、分布式环境软件、服务与计算机的应用软件以及所提供的服务等,文档包括应用表格、合同、手册、操作手册等。软件管理系统必须将它们表示出来,才能对其进行管理。软件资源管理,是指优化管理信息的收集,对企业所拥有的软件授权数量和安装地点进行管理。还包括软件分发管理,指的是通过网络把新软件分发到各个站点,并完成安装和配置工作。
要进行企业的软件资源管理,首先就要先识别出企业中的运行的软件和文档,将其归类汇总、登记入档。在项目管理中,软件资源可重用的程度是CMM衡量的一个重要指标。众所周知,提高软件的重用度也是每一家软件公司所追求的。
首先要搞清楚自己的家底。把各个项目组的负责人召集在一起,把有重用价值的软件模块或控件收集起来,再把相关的资料组织在一起,标注说明、建立索引、由专人负责管理,可重用模块的升级和完善都要建立完整的档案资料,在升级档案中要记录升级前后的主要区别。为重用模块做出贡献的个人都要被记录在册。一个项目在做系统设计任务书时,就要考虑有哪些以往的软件资源可以利用新一轮的开发有那些功能可以做成可重用模块。这样才能很好地管理企业的软件资源。

软件开发的生命周期包括两方面的内容,首先是项目应包括哪些阶段,其次是这些阶段的顺序如何。一般的软件开发过程包括: (12) (13) 、编码(Coding)及单元测试(Unit Test)、 (14) 、安装(Install)、 (15) 等阶段。
软件维护是软件生命周期中持续时间最长的阶段。在软件开发完成并投入使用后,由于多方面的原因,软件不能继续适应用户的要求。要延续软件的使用寿命,就必须对软件进行维护。软件的维护包括纠错性维护和改进性维护两个方面。

单项选择题

Anyone who doubts that children are born with a healthy amount of ambition need spend only a few minutes with a baby eagerly learning to walk or a headp toddler starting to talk. No matter how many times the little ones stumble in their initial efforts, most keep on trying, determined to master their amazing new skill. It is only several years later, around the start of middle or junior high school, many psychologists and teachers agree, that a good number of kids seem to lose their natural drive to succeed and end up joining the ranks of underachievers. For the parents of such kids, whose own ambition is often inseparately tied to their children’s success, it can be a bewildering, painful experience. So it is no wonder some parents find themselves hoping that ambition can be taught like any other subject at school.

It’s not quite that simple. "Kids can be given the opportunities, but they can’t be forced. " says Jacquelynne Eccles, a psychology professor at the University of Michigan who led a study examining what motivated first-and seventh-graders in three school districts. Even so, a growing number of educators and psychologists do believe it is possible to unearth ambition in students who don’t seem to have much. They say that by instilling confidence, encouraging some risk taking, being accepting of failure and expanding the areas in which children may be successful, both parents and teachers can reignite that innate desire to achieve.

Dubbed Brainology, the unorthodox approach uses basic neuroscience to teach kids how the brain works and how it can continue to develop throughout life. The message is that everything is within the kids’ control, that their intelligence is malleable.

Some experts say our education system, with its p emphasis on testing and rigid separation of students into different levels of ability, also bears blame for the disappearance of drive in some kids. Some educators say it’s important to expose kids to a world beyond homework and tests, through volunteer work, sports, hobbies and other extracurricular activities. "The crux of the issue is that many students experience education as irrelevant to their life goals and ambitions. " says Michael Nakkula, a Harvard education professor who runs a Boston-area mentoring program called Project IF (Inventing the Future), which works to get low-income underachievers in touch with their aspirations. The key to getting kids to aim higher at school is to tell them the notion that classwork is irrelevant is not true, to show them how doing well at school can actually help them fulfill their dreams beyond it. Like any ambitious toddler, they need to understand that they have to learn to walk before they can run.

Some experts suggest that many kids lose ambition in school because they are ().

A. cut off from the outside world

B. exposed to school work only

C. kept away from class competition

D. labeled as inferior to others
