PMI-SP Question #345: Real Exam Question with Answer & Explanation

The correct answer is A. As workers complete the installation, efficiency will increase and durations will decrease.. 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 soft

Question

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?

Options

  • AAs workers complete the installation, efficiency will increase and durations will decrease.
  • BAs workers complete the installation, errors and risks will increase the actual completion.
  • CAs workers complete the installation, effort will diminish and efficiency will decrease.
  • DAs workers complete the installation, labor will diminish so duration will increase.

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.
