When it comes to estimating the cost of an agile project, it is essential to understand the principles and methods behind agile development. Agile is a project management approach that emphasizes flexibility, collaboration, and incremental development. Rather than following a traditional “waterfall” model, where all requirements and outcomes are defined upfront, an agile project breaks the work into smaller, manageable pieces known as iterations. Each iteration involves a cycle of planning, executing, and reviewing, allowing for continuous feedback and course correction.
Estimating the cost of an agile project requires a different mindset compared to traditional project management. Due to the iterative nature of agile development, the end result may not be fully known at the beginning of the project. Instead of attempting to estimate the cost of the entire project upfront, agile teams focus on estimating the effort required for each iteration. Estimation techniques such as story points or planning poker are commonly used to estimate the complexity and effort required for each user story or feature. These estimation methods are based on relative comparisons rather than absolute values, which allows for more flexibility and adaptation as the project progresses.
In addition to estimating the effort for each iteration, an agile project also takes into account the cost of the project team. Traditional approaches may rely on a fixed team size for the duration of the project, whereas agile recognizes that team composition may vary based on skills required for different iterations. As a result, the cost estimation of an agile project factors in the resources needed for each phase and iteration of development.
In conclusion, estimating the cost of an agile project involves a different approach compared to traditional project management. Instead of attempting to estimate the cost of the entire project upfront, agile teams focus on estimating the effort and resources required for each iteration. The iterative nature of agile development allows for flexibility and continuous adaptation, making it more suitable for complex and evolving projects. By using estimation techniques such as story points and adjusting team composition as needed, an accurate estimate can be produced to guide the development process.
软件项目管理 6.9.敏捷估算法 大家好，这节我们学习软件项目管理敏捷估算法既Story point估算方法大家知道，敏捷项目的需求采用story进行描述，那么工作量的估算则采用Story point估算方法
Story point概念为：即故事点，用来度量实现一个Story需要付出的工作量的相对估算
所以我们关注最后得到的相对估算结果，例如估算 故事A为1个Story Point,故事B为2个Story Point,则B的工作量是A的两倍
Story Point估算是一个相对估算的过程，需要确定相对的估算标准
这里给出两个常用的标准，第一个是斐波那数列等级标准，第二个是2的N次方等级数列标准
实践过程当中，我们常以斐波那数列7个等级数列来进行故事点的估算
七个等级分别为：01235813
估算过程如下：
采取SPM项目为例，其中注册功能预估值为3个Story point，而登录功能比注册功能的工作量略少，所以估计值为2个Story point，而人员管理功能比注册功能略多，所以估计值为5个Story point
最后我们介绍一个快速的估算方法过程如下：
如果团队成员对放置的Story不满意，例如下图是最后的排列结果，问号列下有个story9，暂时无法估算
接下来就要计算每一列的story个数，并且乘以所在列值，从而得到所有的故事点，如下图所示：通过敏捷-快速估算方法最后得出的结果是95，其中不包括story9工作量
到这里，第六章 第9节敏捷估算法就讲解完毕了！下一节介绍成本预算~
