澳洲论文代写:敏捷和瀑布模型的比较分析

研究表明,大多数类型的开发失败可能是因为群体形成中存在的问题(Bricaud, 2012)。在敏捷方法的情况下,团队会更频繁地碰面,而不像瀑布方法,团队以业务分析师、业务开发人员、程序员、测试人员等形式划分。缺点是太多的小组会议会占用很多时间。

第三个更重要的特征是,与传统瀑布方法相比,敏捷方法在上下文中可以更少出错(Rob, 2004)。这是因为敏捷迭代确保部分测试可以作为迭代本身的一部分来完成。然而,在瀑布方法的情况下,测试本身被分配了一个单独的部分(Balaji和Murugaiyan, 2012)。然而,敏捷所提供的方便和无错误的特性也可能是一个缺点,因为测试是通过迭代进行的,回顾起来所花费的时间可能会增加。

敏捷具有灵活性的特征,并且可以包含需求,即使开发正在进行中,而瀑布方法并非如此(Verner, & Evanco, 2005)。由于敏捷是灵活的,客户的满意度提高了,但是在瀑布模型中,在开发模块完成之前不允许修改。现在包含许多需求的缺点是,这会导致开发和生产团队负担过重(Cole, and Matsumiya, 2007)。

瀑布模型中还应该考虑的敏捷的最后一个特性是隔离(Fowler和Highsmith, 2001)。敏捷允许更好地划分和隔离数据模块。瀑布方法还允许一定数量的数据隔离,但在实现阶段,隔离可能会更接近。在敏捷的情况下,模块的隔离可以被隔离到最后的绑定时间,因此这对于开发人员和客户来说也是一种解脱。这也可能是一个骗局,因为最终的最终图片和模块的逻辑完成不会在项目实施的最后完成。

Research studies show that most type of development failures might occur because of the issues that exist in group forming (Bricaud, 2012). In the case of the Agile methodology the group meets are more frequent, unlike the waterfall methodology where the groups are divided in the form of business analysts, business developer, programmers, testers and more. The con is that too many group meetings can take up a lot of time.
The third more important characteristic is that of how Agile can be more error free in context compared to that of traditional waterfall method (Rob, 2004). This is because Agile iterations ensures that part of the testing might be done as part of the iterations itself. However, in the case of the waterfall methodology, testing is assigned a separate part in itself (Balaji, and Murugaiyan, 2012). However, the same convenience and error free nature that Agile affords could also be a con, as testing is carried out through iterations the time taken might increase in retrospect.
Agile has the characteristic of flexibility and can include requirements, even when the development is in progress and this is not the case in the waterfall methodology (Verner, & Evanco, 2005). Since Agile is flexible, the client satisfaction is increased, however in the waterfall model the modifications would not be allowed till the development module is completed. Now the cons of including many requirements are that it leads to the situation of an overburdened development and production team (Cole, and Matsumiya, 2007).
The final characteristic of Agile that should also be considered in the waterfall model is that of segregation (Fowler, and Highsmith, 2001). Agile allows for better partitioning and segregation of the data modules. The waterfall methodology also allows for a certain amount of data segregation, but in the implementation stage the segregations might come closer. In the case of Agile, the segregation of modules can be segregated till the final bind time, and hence this is a relief for developers and clients likewise. This could also be a con as the final end picture and logical completion of module would not be done till the very end of the project implementation.
