在迭代期间，项目团队会遇到可能导致任务完成延迟的问题。同一项目中的另一个团队需要按时完成任务，以满足他们的计划。项目经理如何解决这个问题？
During an iteration, a project team encounters problems that may cause a delay in task completion. Another team within the same project needs the task to be completed on time in order to meet their schedule. What can the project manager do to resolve this problem?
A ：坚持让项目团队稍微努力一点以便按时完成，以免耽误其他团队的工作。 Insist that the project team work a bit harder to complete on time, in order to avoid delaying the work of other teams.
B ： 与产品负责人合作，重新确定迭代待办事项列表的优先级，以免耽误其他团队的工作。 Work with the product owner to reprioritize the iteration backlog, so that it does not delay work by other teams.
C ：增加迭代的长度，并向项目团队添加额外的资源，这样他们就可以在适当的最后期限前完成任务。 Increase the iteration length, and add additional resources to the project team, so that they can meet the appropriate deadlines.
D ：要求团队成员在迭代过程中尽其所能，并在迭代完成后进行回顾。 Ask team members to perform to the best of their abilities during the iteration, and engage in a retrospective after completion of the iteration.
