You are the project manager of the NHT Project. This project has 12,345 office doors to install
throughout a campus. Each of the doors costs the project $456 and requires special hardware to
electronically lock and open the doors. You’ve gathered the project team before they begin the
installation for a hands-on training. As a group you and the project team install 50 doors following
a checklist of instructions so that every door will be installed exactly the same throughout the
campus and with minimal waste. This is an example of what project execution technique?

A.
Preventive action

B.
Defect repair validation

C.
Implemented corrective action

D.
Quality control

Explanation:
This is an example of a preventive action as you’re working with the team before they install the
doors to train them on the installation. The checklist is a quality control tool but the question was
asking for a project execution activity. Preventive and corrective actions are part of project
execution.
Answer option D is incorrect. Quality control is a controlling and monitoring process, not an
executing process.
Answer option B is incorrect. The defect repair validation comes after the project team has
corrected an error – something that has not occurred in this instance.
Answer option C is incorrect. Corrective action is a response to something that needs to be
corrected in the project.
