nowadays, we can see some boys and girls who live in a small world of their own. they bury themselves among books and are proud of themselves. they think that it will make them lose their face if they do housework for they often think themselves very noble.
these young people are wrong. in my opinion every student should have a knowledge of housework. after all, they will have a family of their own, and they should do their part in keeping a good home. boys should also learn to do housework, for what will they do if they remain single? though not all boys remain single,yet they will be very helpful in the family if they know some housework. anyhow they will not lose anything, but, on the contrary, they will gain something useful.
for what i said above, we can find some eamples of our fellow-students studying abroad. all young men do housework as girls do. someone would argue that we can employ servants. this is true.however, what shall we do if the servant leaves us and all things are left to ourselves? we just cannot leave our clothes as they are and let worms and ants eat them up. and what can we do it we go and study in a foreign country where servants are out our means to employ? we must work for ourselves. why not start to learn to do housework now or else it will be too late? everyone should learn to do housework. what do you think about my idea, boys and girls?

软件变更管理主要涉及到软件更改的申请、软件更改的批准、软件更改、软件问题归零、软件更改验证及评审等环节。针对软件变更管理中的薄弱环节，以下内容将说明软件配置变更管理中很容易忽视的几个问题，并给出提高软件质量的建议。
（1）软件变更缺少相应级别的评审
实施软件变更的人员在进行完软件的变更之后，由于缺乏对软件更改部分的验证工作，容易导致软件实际更改内容与预期更改内容不一致，甚至由于软件更改描述内容过于简单，导致软件测试人员认为软件只是更改了参数文件等相关内容，而实际上却更改了其他文件，从而造成了软件中可能隐藏的缺陷没有能够暴露。因此，软件变更之要后要进行相应级别的评审，而不能走形式主义。
（2）软件变更管理需要模块化思想
从事软件测试的人员一定会发现，上一版本软件测试提交的问题报告单，在下一版本软件中仍然没有归零，于是软件测试人员纷纷抱怨软件的质量跟踪不到位、软件质量人员没有尽到应有的.责任。可各种软件规章制度实在太多，也不可能把质量人员的质量职责细化得太精确。因此，软件变更管理需要进行模块化管理，将软件变更管理内容按照一定类型分解为不同的模块，让软件变更流程上相关人员按照模块化的思想进行软件变更流程处理，以更好的保证软件质量，从而很好的控制了一些客观因素对软件变更过程质量的影响。
（3）软件变更管理应具有可追溯性
在国有企事业单位软件研制的过程中，软件往往需要变更多次之后才能形成最终交付用户的产品，可软件研制除了注重结果之外，也应该注意过程。因为中间过渡版本软件是企业的积累，它可以让软件研制人员总结研制过程中的经验、让新进人员吸取研制过程中的精华知识。因此，对软件的变更管理要有可追溯性。
