Project Management Professional (PMP) Exam Practice – Question1454

You are leading a research project that will require between 10 and 20 aerospace engineers. Some senior-level aerospace engineers are available. They are more productive than junior-level engineers, who cost less and who are available as well. You want to
determine the optimal combination of senior-and junior-level personnel. In this situation, the appropriate technique to use is to______________


A. Conduct a design of experiments
B. Use the Ishikawa diagram to pinpoint the problem
C. Prepare a control chart
D. Analyze the process using a Pareto diagram

Correct Answer: A

Explanation:

Explanation:
This technique is used to identify which variables have the most influence. It is a statistical method to identify the factors that may influence specific variables of a product or process under development or in production. For example, roller blade designers might
want to determine which combination of number of wheels and titanium ball bearings would produce the most desirable “ride” characteristics at a reasonable cost. This technique, however, can be applied to project management issues such as cost and schedule
trade-offs. An appropriately designed “experiment” often will help project managers to find an optimal solution from a relatively limited number of options, and often it help to determine the number and type of tests to use and their impact on quality.
