你最近被分配到一个从未合作过的 Scrum 团队担任产品负责人。一周后，你的公司的一位经理与你联系，并请你确认该项目将在3月6日之前完成。他说他查看了你的团队给出的预估完成时间，需要你们承诺项目在该确切日期完成。在这种情况下出现了什么问题？
Recently you have been assigned as a Product Owner to the Scrum team that you had never worked with before. One week later one of your company's managers approaches you and asks to confirm that the project will be finished by the 6th of March. He says that he reviewed estimates given by your team and needs a commitment to guarantee it will be finished to the exact date. What is the most likely problem in this situation?

A.经理应该去找Scrum主管，而不是你。 The Manager should approach a Scrum Master, not you.

B.许多经理将预估时间与承诺时间混淆。一旦团队预估了一个时间，就要求他们承诺实现。 Many managers confuse estimates with commitments. As soon as a team expresses an estimate they are forced to commit to it.

C.你最近才被分配到该项目，因此还无法做出任何承诺。 You have been assigned to the project recently therefore you are not able to make any commitments yet.

D.敏捷团队不承诺在特定日期完成项目。 Agile teams don't make any commitments to specific dates.

知识点：PMP敏捷专项练习题（一）

参考答案：B

解析：《敏捷实践指南》，5.4.1敏捷团队的衡量结果 选项A错误。产品负责人与相关方和客户合作，因此经理去找产品经理是正确的。 选项B正确。敏捷倾向于使用基于经验和价值的衡量指标，而不是预测型衡量指标。基准通常是尝试预测的产物，比如承诺。但是在敏捷中，团队的估算最多限于未来几周时间。团队不能 100% 确定自己能交付什么，因为他们无法知道意外情况。因此估算和承诺是两个概念，外部干系人不应该混淆。 选项C错误。是否做出承诺与是否刚被分配到团队没有必然关系。 选项D错误。“don't make any commitments”的说法过于绝对。
