2. What is the purpose of the work breakdown structure (WBS)?
The WBS allows the project manager to delegate responsibility of all of the project activities.
The WBS is a narrative description of the work required for the project.
The WBS describes the total program as a summation of subdivided elements.
The WBS is a statement of what will be made, how many units will be made, and when they will be made.

工作分解結(jié)構(gòu)(WBS)的目的是
WBS允許項(xiàng)目經(jīng)理承擔(dān)所有項(xiàng)目活動(dòng)的責(zé)任.
WBS是項(xiàng)目所需工作的文字性描述
WBS將整個(gè)程序描述為細(xì)分要素的匯總
WBS 描述了做什么， 做多少以及什么時(shí)候做

6. Cost Variance (CV) is which of the following equations?
CV=BCWP-BCWS
CV=BCWP-ACWP
CV=SV/BCWS
A and c

費(fèi)用偏差的公式為

成本偏差（CV）=已完成工作預(yù)算成本（BCWP）-完成工作實(shí)際成本（ACWP）
成本偏差（CV）=進(jìn)度偏差（SV）除以計(jì)劃工作預(yù)算成本（BCWS）
A和c

7. Cost controls can be best described by which of the following?
The process of developing the future trends along with the assessment of probabilities, uncertainties, and inflation that could occur during the project
The process of assembling and predicting cots of project over its life cycle
The process of establishing budgets, standards, and a monitoring system by which the investment cost of the project can be measured and managed
The process of gathering, accumulating, analyzing, monitoring, reporting, and managing the costs on an on-going basis

以下哪一條最貼切的描述了成本控制?
是對(duì)未來項(xiàng)目進(jìn)行過程中發(fā)生的可能性，不確定性及夸大性進(jìn)行趨勢(shì)估定的方法.
是組合并預(yù)計(jì)項(xiàng)目超出其生命周期的費(fèi)用的方法
是制定預(yù)算，標(biāo)準(zhǔn)及監(jiān)測系統(tǒng)以衡量并管理項(xiàng)目投資成本的方法
是在不斷進(jìn)行的基礎(chǔ)上搜集，積累，分析，檢測，報(bào)告并管理成本的一種方法.

8. Which one of the following is NOT a trade-off decision that must be made in the development of the project plan?
Whether to use skilled or unskilled laborers.
The amount of profit vendors should make versus the profit other vendors have received in the past.
Manufacturing in-house or sub-contracting ort the work.
The importance of cost versus quality.

以下哪一項(xiàng)不是項(xiàng)目計(jì)劃過程中可能發(fā)生的換位權(quán)衡的決定?
是否使用有技能的勞動(dòng)力或者無技能的勞動(dòng)力
賣方應(yīng)當(dāng)獲得的利潤額同其他賣方在過去獲得的利潤比較
自己制造或者分包
成本重要性同質(zhì)量比較
