Which one of the following estimate types is a form of expert judgment?

  1. Parametric estimate
  2. Analogous estimate
  3. Bottom-up estimate
  4. Definitive estimate

Answer(s): B

Explanation:

An analogous estimate is a form of expert judgment because it relies on historical information. The historical information, assuming that it is accurate, serves as the conduit to the expert that created the historical information.
Answer option C is incorrect. A bottom-up estimate creates an activity duration estimate for each work package in the WBS.
Answer option A is incorrect. Parametric estimating uses a parameter, such as 10 hours per fixture installation, as a base to predict the duration of the project.
Answer option D is incorrect. A definitive estimate, also known as a bottom- up estimate, accounts for the cost of each work package.



You are the project manager of the NHA Project. This project is expected to last one year with quarterly milestones throughout the year. Your project is supposed to be at the third milestone today but you're likely only 60 percent complete. Your project has a BAC of $745,000 and you've spent $440,000 of the budget-to-date.
What is your schedule performance index for this project?

  1. 80
  2. 1.02
  3. 102
  4. 0.80

Answer(s): D

Explanation:

The schedule performance index can be found by dividing the earned value by the planned value. In this project, it's $447,000 divided by the $558,750 for a value of 0.80. Schedule performance index (SPI) is the measure of schedule efficiency on a project. It is used in trend analysis to predict future performance. SPI is the ratio of earned value to planned value. The SPI is calculated based on the following formula:

SPI = Earned Value (EV) / Planned Value (PV)
If the SPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The SPI value of 1 indicates that the project is right on target.

Answer option A is incorrect. "80" is not the same value as ".80".
Answer option B is incorrect. 1.02 is the cost performance index.
Answer option C is incorrect. 102 is not a valid calculation for this question.



Fill in the blank with an appropriate phrase.
The __________ includes a description of any collateral services required, such as performance reporting or post-project operational support for the procured item.

  1. procurement SOW

Answer(s): A

Explanation:

The procurement SOW consists of a description of som collateral services required, such as performance reporting or post- project operational support for the procured item. The procurement SOW is revised and refined as required when it moves through the procurement process until incorporated into a signed contract award.



Mark is the project manager of the GHQ Project. He is happily reporting that his project has a schedule performance index of 2.12. Management, however, does not think this is good news.
What is the most likely reason why management does not like an SPI of 2.12?

  1. It is not good news because a larger number means the schedule duration estimates were likely to be wrong to begin with.
  2. They likely do not understand the SPI formula.
  3. It is not good news, as the number should be closer to 100 than 0.
  4. It is good news, but Mark may have large cost variances to achieve this value.

Answer(s): A

Explanation:

Cost and schedule performance indexes should be as close to 1 as possible. A larger value, such as 2.12, means that the schedule duration estimates were likely bloated or incorrect to begin with.
Answer option B is incorrect. This is not the best choice for this question.
Answer option C is incorrect. The number should not be close to 100; it should be close to 1.
Answer option D is incorrect. While Mark may have crashed the schedule and driven up costs to achieve the SPI value, a more likely reason is that the time estimates were bloated.



You are the project manager of the BHG Project. You are creating a network diagram as shown in the figure:



Mary, a project team member, reports that an identified risk is likely to happen in the project that will affect the completion date of Activity D . She reports that the risk event will likely cause the duration of the activity to increase by six days. If this happens what is the earliest the project can complete?

  1. 32 days
  2. 29 days
  3. 27 days
  4. 26 days

Answer(s): D

Explanation:

If Activity D increases by six days, the duration of the project will not change. There is 11 days of float available for Activity D so it may delay by six days without affecting the project end date.
What is float? Float or total float (TF) is the total amount of time that a schedule activity may be delayed from its early start date without delaying the project finish date, or violating a schedule constraint. It is calculated by using the critical path method technique and determining the difference between the early finish dates and late finish dates. Answer options A, B, and C are incorrect. These are not valid answers for the question.
