Question 1

Which quality control tool is used to determine whether a process is stable and operating within predictable limits over time?

Accepted Answer

Control chart

Answer

Control charts display process data over time against upper and lower control limits to determine if a process is stable and statistically predictable.

Question 2

A cause-and-effect diagram (Ishikawa/fishbone diagram) is primarily used to:

Accepted Answer

Identify potential root causes of a problem

Answer

The cause-and-effect diagram visually maps potential root causes of a defect or problem, organized by categories such as people, process, materials, and equipment.

Question 3

What is 'statistical sampling' used for in project quality control?

Accepted Answer

To inspect a representative subset of items rather than the entire population

Answer

Statistical sampling inspects a representative portion of a population, providing reliable quality data more cost-effectively than 100% inspection.

Question 4

In a quality control chart, what does a 'control limit' represent?

Accepted Answer

The statistical boundary beyond which a process is considered out of control

Answer

Control limits define the expected range of variation for a stable process; data points outside these limits signal potential process instability requiring investigation.

Question 5

During project execution, a quality audit is best described as:

Accepted Answer

A structured review to identify gaps between current practices and quality standards

Answer

A quality audit systematically examines whether quality processes are being followed correctly and identifies areas for improvement and compliance.
