44. 有一種縮短項目進(jìn)度的辦法是在項目設(shè)計階段的每個活動上安排3 個開發(fā)員而不是2 個，雖然你考慮這種辦法，但設(shè)計團(tuán)隊將會擴(kuò)大一倍。這種方法往往：
A. 降低生產(chǎn)率
B. 提高生產(chǎn)率
C. 降低了質(zhì)量審計的必要，因此減少了整個的資源成本
D. 隨著資源增加，生產(chǎn)也按比例增加了
參考答案：A。人員增加，導(dǎo)致溝通渠道增加，效率變低。參見《PMBOK指南》第五版第292 頁

45.Which of the following scheduling techniques incorporates a form of risk assessment?
A． Analogous estimating
B． Program Evaluation and Review Technique (PERT)/three point estimate
C． Precedence Diagramming Method (PDM)
D． Critical Path Method (CPM)
45. 以下進(jìn)度計劃制訂技巧中何種包含某種形式的風(fēng)險評估？
A. 類比估算
B. 計劃評審查技術(shù)/三點(diǎn)估算
C. 單代號圖方法（PDM）
D. 關(guān)鍵路線法（CPM）
參考答案：B。三點(diǎn)估算法考慮估算中的不確定性和風(fēng)險。參見《PMBOK 指南》第五版第170 頁

46．A project plan results in a project schedule that is too long. If the project network diagram cannot change but you have extra personnel resources, what should you do?
A. Fast track the project
B. Level the resources
C. Crash the project
D. Perform a value analysis
46. 一個項目規(guī)劃的結(jié)果發(fā)現(xiàn)項目的規(guī)劃進(jìn)度要比預(yù)計要求的進(jìn)度表需要更多時間，如果項目的網(wǎng)絡(luò)圖不能夠修改，但是你有額外的職員資源，你應(yīng)該做什么？
A． 快速跟進(jìn)此項目
B． 資源平衡
C． 趕工此項目
D． 進(jìn)行價值分析
參考答案：C。進(jìn)度落后，需要進(jìn)度壓縮。快速跟進(jìn)會改變活動間的邏輯關(guān)系，即改變網(wǎng)絡(luò)圖。趕工是通過增加資源，來壓縮活動本身的時間，不會改變邏輯關(guān)系。參見《PMBOK 指南》第五版第181 頁

47. It is crucial that your project team finish your project on time. Your team is using a technique to account for limited resources. You have also added a project buffer before the end date and feeding buffers before each critical task. What technique are you using?

B. PERT
C. critical chain
D. earned value
47. 你的項目團(tuán)隊必須按時完成項目。你的團(tuán)隊使用了一種考慮有限資源的技術(shù)，在最終日期前添加了緩沖，并在關(guān)鍵活動上加入緩沖。這種技術(shù)叫做：
A. 關(guān)鍵路徑分析

48. 質(zhì)量是你項目的主要限制。為了不使項目小組成員對時間感到有太大的壓力，并避免進(jìn)度延誤的風(fēng)險，你決定采用下列哪種估算活動持續(xù)時間的工具？
A. 專家判斷
B. 基于定性的歷時
C. 儲備分析
D. 類比估算
參考答案：C。“為了不使項目小組成員對時間感到有太大的壓力，并避免進(jìn)度延誤的風(fēng)險”--應(yīng)該多一些緩沖，即儲備。參見《PMBOK 指南》第五版第171 頁

49．Three-Point Estimates:

B. is event oriented with activity on arrow
C. will have only one time estimate per activity

49. 三點(diǎn)估算法:
A．一般有三種估計時間幫助預(yù)測活動歷時期望值

C．每項活動僅有一個時間估計值

參考答案：A。進(jìn)度壓縮的前提是不縮減項目范圍。參見《PMBOK指南》第五版第181 頁
