CQE (CQE) Fundamentals 5

Question 1

Which of the following BEST describes 'concurrent engineering' in a product development context?

Accepted Answer

Simultaneous development of product and process design to reduce time-to-market

Answer

Concurrent engineering involves simultaneous development of product and process design, reducing cycle time and catching issues earlier.

Question 2

In Design of Experiments (DOE), a 'full factorial' design means:

Accepted Answer

Every possible combination of factor levels is tested

Answer

A full factorial design tests all possible combinations of every factor level, allowing estimation of all main effects and interactions.

Question 3

The acceptable quality limit (AQL) in a sampling plan represents:

Accepted Answer

The worst quality level still considered acceptable for routine acceptance

Answer

AQL is the worst tolerable process average when a continuing series of lots is submitted for acceptance sampling.

Question 4

Which of the following quality improvement methodologies follows the DMAIC problem-solving framework?

Accepted Answer

Six Sigma

Answer

Six Sigma uses the DMAIC (Define, Measure, Analyze, Improve, Control) framework for structured problem solving and process improvement.

Question 5

A process produces 3.4 defects per million opportunities (DPMO). This corresponds to which sigma level?

Accepted Answer

6 sigma

Answer

Six Sigma quality by definition corresponds to 3.4 DPMO, which accounts for a 1.5 sigma long-term process shift.
