软件配置管理的目的在于建立和维护软件项目生命周期内软件产品的完整性。配置管理工作如果做不好,很容易产生软件质量问题。
last weekend we went to the countryside to have a picnic.we took several sandwiches and some bottles of water with us for lunch. of course we didn't forget to take some fruit and we even took some tomatoes and cucumbers.
we left home quite early in order to avoid the traffic jam.about two hours later, we came to a nice place. it was near a river. we put our bicycles under the trees and went swimming. it was a very hot day. the water was very refreshing.
after having a swim, we had lunch in the cool shade under the trees. then we went for a walk. we didn't come back home until the night fell.
上周末,我们去乡下野餐。我们带上了几个三明治和几瓶水午饭时吃。当然我们也没有忘记带上一些水果。我们甚至还带了几个西红柿和几条黄瓜。
为了避开交通高峰,我们很早就出发了。大约过了两个小时,我们来到了一个不错的.地方。它附近有一条河,我们把车子放在树下就去游泳。天气很热,河水使人振奋。
游完泳,我们在树荫下吃了午饭。然后我们去散步。直到夜幕降临,我们才回家。
it took us about two hours by bike to get to the nice place in the countryside. there was a rive there. the water was clean and it was a good place to swim. we threw our bikes on the ground
and jumped into the water. it was hot, but the water made us refreshed. after we swam around:'the river, we were tired.
we took out the sandwiches and water, and had our picnic in the shade under the trees. the most popular food are sausages and tomatoes.
after lunch we took a walk. there we saw many beautiful flowers and GREen grass. we smelled sweet air. how nice the picnic was!
我们骑车花了约两个小时,终于到了野外那个美丽的地方。那里有一条小河,河水清澈,真是个游泳的好地方。我们把自行车往地上一搁,就跳进河里。天气真热,河水让人感到舒爽。游了几个来回,我们有些累了。
我们拿出准备好的三明治和水,开始在树阴下野餐。最受欢迎的食品是香肠和西红柿。
午饭后,我们散步。在那儿我们看见许多漂亮的花和碧绿的草,我们闻到空气的芬芳。多么愉快的野餐啊!

The picture shows us a dialogue between a father and a son. The son told his father, “Dad, I’m a bit worried about disposing of nuclear waste”. While his father told him, “If you can empty the dustbin here you can do anything”. It reveals the importance of doing small things well before undertaking something big. There is also an old Chinese saying to go with this that a person can’t sweep the world before he can sweep his own room.
I agree on the point that it is of great importance for a person to do small things well before undertaking something big. First of all, doing small things well entail the qualities that needed in doing great things such as patience and ability of controlling time. For example, when we sweep our room, we need to manage our time and energy reasonably. Accordingly, if we sweep a bigger room, for example, a classroom with our classmates, we should learn how to cooperate and allot assignments as well. And a big advantage is that we can draw useful lessons from the failure of performing well because they didn’t cost a lot.
In another word, though these things seem trivial, they reinforce our manipulative ability and thus our understanding to the world. Therefore, we should not ignore the small things.
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。
