PMI Quality Planning & Control Charts 3

Question 1

When using a c-chart, what is being measured?

Accepted Answer

The number of defects per inspection unit

Answer

A c-chart monitors the count of defects (nonconformities) per unit where the sample size is constant, following a Poisson distribution.

Question 2

In quality management, 'prevention costs' are best described as:

Accepted Answer

Costs to avoid defects from occurring in the first place

Answer

Prevention costs include planning, training, and process improvement activities undertaken before production to avoid defects from ever occurring.

Question 3

What is the purpose of the 'Plan-Do-Check-Act' (PDCA) cycle in quality management?

Accepted Answer

To provide a structured framework for continuous process improvement

Answer

The PDCA cycle (Deming Cycle) provides a repeating four-step iterative process for continuously improving products, processes, and services.

Question 4

A project team uses a scatter diagram to analyze two variables. What conclusion can be drawn if the data points form a tight upward-sloping line?

Accepted Answer

There is a strong positive correlation between the two variables

Answer

A tight upward-sloping scatter diagram indicates a strong positive correlation, meaning as one variable increases the other tends to increase — though correlation does not imply causation.

Question 5

Which PMI process group does 'Control Quality' belong to?

Accepted Answer

Monitoring and Controlling

Answer

Control Quality is part of the Monitoring and Controlling process group and focuses on measuring actual results against quality standards.
