- B.水晶法
- C.并列争球法
- D.自适应软件开发
正确答案及解析
正确答案
解析
并列争球法就是我们通常所说的 Scrum。Scrum 是一个增量的、迭代的开发过程。在这个框架中，整个开发过程由若干个短的迭代周期组成，一个短的迭代周期称为一个 Sprint，每个Sprint 的建议长度是 2 到 4 周。在 Scrum 中，使用产品 Backlog 来管理产品的需求，产品backlog 是一个按照商业价值排序的需求列表，列表条目的体现形式通常为用户故事。Scrum团队总是先开发对客户具有较高价值的需求。挑选的需求在 Sprint 计划会议上经过讨论、分析和估算得到相应的任务列表，我们称它为 Sprint backlog。在每个迭代结束时，Scrum 团队将递交潜在可交付的产品增量。
