PMI-ACP练习题(22)

1、Ethan and his team just highlighted two processes that each have a lead time an order of magnitude more than any other processes in the system. When an agile team uses value stream mapping like Ethan’s team it is an example of a A. Product roadmap B. Kanban board C. Process analysis technique D. Iteration plan 伊桑的团队着重两个流程，这两个流程都有前置时间，比系统中的其他任何流程都重要。他们团队的价值流程图是以下哪一项的例子？

• A：产品路线图

• B：看板

• C：过程分析技术

• D：迭代计划

C解析：价值流程图是一项协作性地流程分析技能，一支功能多样的团队绘制一个流程来识别浪费发生的地方并且确认可完善的地方。它是流程分析技能的一个例子。 和价值流程图类似，流程图也用于绘制一个流程来识别瓶颈（即流程会减缓和产生库存的地方）。

5、What delivery concept does agile pride itself on and having a definition of frequent delivery of working products, which are successively improved, to a customer for immediate feedback and acceptance? A. Iterative delivery B. Sprint delivery C. Incremental delivery D. Cyclical delivery 以下哪一项交付概念，是敏捷引以为豪的，并被定义为及时反馈和接纳，频繁向客户交付可持续改进的工作产品？

6、Mike, as the product owner, likes being able to provide immediate feedback to the agile team regarding the latest version of a product. Although Mike has other opportunities to provide feedback, like in the daily stand-up meeting and during iteration planning, this particular type occurs after the delivery of a new product which occurs at frequent, set intervals. What type of delivery concept provides this type of customer feedback? A. Iteration delivery B. Defect reduction delivery C. Prototype delivery D. Incremental delivery 产品负责人迈克，倾向于对产品的最新版本向敏捷团队提供及时反馈。虽然迈克还有其他途径可提供反馈，比如在每日站立会议上和在迭代计划期间，但是这种方式仍会经常在新产品交付后发生。以下哪一类型的交付概念提供这种客户反馈？

• A：迭代交付

• B：缺陷降低交付

• C：原型交付

• D：增量交付

D解析：增量交付往往是在每一个冲刺或迭代的末期对交付产品提供反馈，使客户评价产品并提出新的需求，以确保客户得到有价值和质量的产品。

11、What is rolling wave planning and how does it relate to progressive elaboration? A. Rolling wave planning involves planning for an entire release at the beginning of a project. Progressive elaboration assumes that while customer requirements may change, they will not impact the initial rolling wave plan. B. Rolling wave planning involves a retrospective review of plans from the previous two iterations. Momentum from these two iterations, typically interpreted as velocity, from a prediction wave which can be used to plan the next iteration. Progressive elaboration assumes that the wave will grow in power as the project progresses. C. Rolling wave planning involves planning in waves or phases. Only the next few iterations are planned in detail and iterations more distant are planned only at a high-level. Progressive elaboration is continuous planning that assumes that details and requirements will be better refined later and will be incorporated into the planning process at the appropriate time D. Rolling wave planning and progressive elaboration are both antiquated traditional project management pla
