QUESTION: 173

Tom works as the project manager for Blue Well Inc. He spends the majority of his time communicating with team members and the project stakeholders. Various communication skills are involved in the communication processes.
Which communication skills are involved in this process? Each correct answer represents a part of the solution. Choose all that apply.

Internal and External
Vertical and Horizontal
Confronting and problem solving
Formal and Informal

Answer(s): A,B,D

Explanation:

These are some communication activities that Tom uses to communicate with the team and the stakeholders.
Communications skills are part of general management skills and are used to exchange information.
Communication has many dimensions:
Written and oral, listening, and speaking
Internal (within the project) and external (customer, the media, the public) Formal (reports, briefings) and informal (memos, ad hoc conversations) Vertical (up and down the organization) and horizontal (with peers) Communication is the most important skill that a project manager must posses. It is the single most important characteristics of a top-class project manager. Project managers must communicate well in order to integrate and maximize the performance of team members. Oral and written communications are the backbone of every successful project. During different phases of a project, a project manager requires to communicate through different manners (for example, documentation, meeting updates, etc.) and he must ensure that the information communicated is explicit, clear, and complete.

Answer option C is incorrect. It is a technique to resolve conflict that arises while communicating with different parties.

QUESTION: 174

Frank is the project manager of a construction project. In this project, Frank has elected to allow the interior design phase of the project to overlap with the pool construction phase of the project. Normally, Frank would not allow these two phases to overlap, but for this project, he has elected to do so in order to compress the project schedule.
What is this schedule compression technique called?

Resource leveling heuristic
Lead time
Fast tracking
Crashing

Answer(s): C

Explanation:

This is an example of fast tracking. Fast tracking allows phases to overlap in order to compress the project schedule.

Answer option D is incorrect. Crashing adds labor to the project in order to complete effort-driven activities in less time.

Answer option B is incorrect. The lead time allows individual activities to overlap, not entire phases.
Answer option A is incorrect. Resource leveling heuristics are rules that limit the amount of time a labor resource may contribute to the project
in a given time period.

QUESTION: 175

You are the project manager of a project that has a budget of $875,000 and you have completed 40 percent of the project work. Due to some errors, however, you have actually spent $425,000 of the budget. Management wants to know what the project's cost performance index is.
What value do you report?

-$75,000
$350,000
.82
-$187,500

Answer(s): C

Explanation:

Cost performance index (CPI) is used to calculate performance efficiencies. It is used in trend analysis to predict future performance. CPI is the
ratio of earned value to actual cost. The CPI is calculated based on the following formula:
CPI = Earned Value (EV) / Actual Cost (AC).

If the CPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The CPI value of 1 indicates that the project is right on target. In this instance it's $350,000 divided by $425,000 for a CPI
of .82.

Answer option B is incorrect. $350,000 is the earned value of the project.
Answer option A is incorrect. -$75,000 is the cost variance for the project.
Answer option D is incorrect. -$187,500 is the predicted variance at the completion of the project.

QUESTION: 176

A project team installs 2,500 light fixtures in a new office building, and each light fixture takes one hour to install. The project manager can predict that it will take 2,500 hours to complete the work. However, which of the following statements most accurately describes this parametric estimate assumption?

As workers complete the installation, efficiency will increase and durations will decrease.
As workers complete the installation, errors and risks will increase the actual completion.
As workers complete the installation, effort will diminish and efficiency will decrease.
As workers complete the installation, labor will diminish so duration will increase.

Answer(s): A

Explanation:

When project team workers complete repetitive tasks, efficiency through learning will diminish the overall duration of the project tasks.
A parametric estimate is an estimate that uses a parameter to predict the costs of the project, such as cost per network drop or cost per software license. Parametric estimating technique utilizes the statistical relationship that exists between a series of historical data and a particular delineated list of other variables.
Answer options B, D, and C are incorrect. These are not the valid statements.
