QUESTION 123

Explanation:
This question is similar to others in this program, but not exactly the same. You may also see this occur on your exam. Carefully read the questions! In this case, we are in the Perform Quality Assurance process.
Completed checklists (choice A) are an output of Perform Quality Control. Quality metrics (choice B) are an output of Plan Quality. Benchmarking (choice C) is a tool of the Plan Quality process. Only the items in choice D are all outputs of the Perform Quality Assurance process.
