supplement existing quality control activities. Which of the following would NOT be appropriate
for this purpose?
A. Quality audits
B. Statistical sampling
C. Pareto diagrams
D. Focus groups
Answer C
Explanation Though quality problems MAY lead to quality assurance efforts, they are not a
MUST. Quality improvement is a result of Perform Quality Assurance, not an input. Rework ( or
defect repair) can be an output of Control Quality. That leaves only quality control measurements,
which are inputs to the Perform Quality Assurance process.
My question is : statistical Sampling is also not tools & techniques of perform quality assurance, hence I think option B is the correct answer than option D? (is Statistical sampling T & T of perform quality assurance process?)
