A. Rolling wave method

B. Earned Value Technique

C. A Manual forecast

A. Cost baseline, requirements traceability matrix

B. Project schedule, agreements

C. Basis of estimates, activity cost estimates

D. Project schedule, resource calendars

 

 

Answers

1.   A - The correct response is 'S' curve. The Cost Performance Baseline is a time-phased budget and is used as a basis to measure, monitor, and control overall cost performance of the project. It is usually displayed in the form of: an S curve and is developed by summing estimated costs by period. [PMBOK
5th edition, Page 213]   [Project Cost Management]

 

2.   B - Contingency Reserves are
estimated costs to be used at the discretion of the project manager to deal
with anticipated, but not certain events. These are also called as "Known unknowns". [PMBOK 5th edition, Page 206] [Project Cost Management]

3.   D - The correct answer is 0.5. The Cost performance Index (CPI) is given by the formula CPI = EV/AC where EV is the Earned Value and AC is the Actual Cost. Earned Value = 50% of $ 50,000 =$ 25,000 since 50% of the project is complete. Hence CPI = 25,000 / 50,000 = 0.5. [PMBOK 5th edition, Page 219] [Project Cost  Management]

4.   C - Although the Earned value technique of determining the balance work in the project is quick and automatic, it is not as valuable or accurate
as the manual forecasting of the remaining work by the project team. This       however is more time-consuming. [PMBOK 5th edition, Page 220] [Project Cost Management]

5.   A - This technique is known as Parametric Estimating and can produce higher levels of accuracy depending on the sophistication, as well as the
underlying resource quantity and cost data built into the model. [PMBOK 5th   edition, Page 205] [Project Cost Management]

6.   D - During the initial stages of the project, the level of information available will be limited. Hence the Rough Order of Magnitude (ROM) estimate
is usually prepared and has an accuracy range of -25% to +75%. [PMBOK 5th edition, Page 201] [Project Cost Management]

7.   A - Management reserves are included in the project's total funds but they are not included in the project's cost performance baseline. [PMBOK 5th edition, Page 214] [Project Cost Management]

8.   D - Interpersonal skills is not a valid choice. The other three choices, namely Variance Analysis, Trend Analysis and Earned Value Performance, are
analytical techniques. [PMBOK 5th edition, Page 91, 92] [Project Integration Management]

9.   B - Control thresholds are variance thresholds for costs or other indicators such as person days and indicate  the agreed amount of variation
allowed. [PMBOK 5th edition, Page 148] [Project Time Management]

10. A - The cost baseline and the requirements traceability matrix
are not inputs to the Determine Budget process. The rest are valid inputs. [PMBOK 5th edition, Page 208] [Project Cost Management]
