Question 1

A cause-and-effect diagram (choose the most inclusive answer)
A) is also referred to as Show cause diagram.
B) is also referred to as flow diagram.
C) is also referred to as opportunity flow diagram.
D) is one of the analytical tools in DMAIC analysis.
E) is also referred to as Pareto diagram.

Accepted Answer

A cause-and-effect diagram is one of the analytical tools used in DMAIC analysis, which is part of the Six Sigma methodology. It is commonly used to identify and analyze the root causes of a problem or issue. The other answer options are not accurate descriptions of a cause-and-effect diagram.

Question 2

Which of the following is a dimension of design quality?
A) Aesthetics
B) Price
C) Quality at the source
D) Distribution
E) Leadership

Accepted Answer

Aesthetics is a dimension of design quality as it pertains to the appearance and visual appeal of the product. Price, quality at the source, distribution, and leadership are all important aspects of a product's overall success, but they are not dimensions of design quality.

Question 3

A cost of quality classification is which of the following?
A) Material costs
B) Prevention costs
C) Variable overhead
D) Direct labor
E) Inventory costs

Accepted Answer

A cost of quality classification includes prevention costs, which are expenses incurred to prevent defects and errors from occurring in the production process. Material costs, direct labor, variable overhead, and inventory costs are not part of the cost of quality classification.

Question 4

Which of the following is the cost of quality classification for costs such as inspection, testing, and other tasks to ensure that the product or process is acceptable?
A) Appraisal costs
B) Prevention costs
C) External failure costs
D) Internal failure costs
E) Checking costs

Accepted Answer

Appraisal costs are the costs associated with evaluating, testing, and inspecting products or processes to ensure they meet quality standards. This includes inspection and testing costs, as well as costs associated with measuring and evaluating quality performance. Therefore, A) is the best choice for this question.

Question 5

Which of the following are basic assumptions that justify an analysis of the costs of quality?
A) Failures are caused.
B) Prevention is more expensive.
C) Performance can be learned.
D) Rules of thumb don't always work.
E) Appraisal costs are less than prevention costs.

Accepted Answer

Failures are caused.

Question 6

Which of the following is the cost of quality classification for costs such as scrap, rework, or repair?
A) Appraisal costs
B) Prevention costs
C) External failure costs
D) Internal failure costs
E) Rework and wastage

Accepted Answer

Internal failure costs refer to the costs incurred due to defects found before the product or service is delivered to the customer, such as scrap, rework, or repair.

Question 7

All except one of the following is an analytical tool for Six Sigma.
A) Flowcharts
B) Pareto Charts
C) Cause-and-effect diagrams
D) DPMO analytics
E) Process control charts

Accepted Answer

All of the tools listed (A, B, C, E) are analytical tools for Six Sigma, so the answer is the one that is not listed, which is DPMO analytics. DPMO (Defects Per Million Opportunities) is a metric used in Six Sigma to measure the level of defects in a process. It is not a tool or technique for analysis.

Question 8

Which of the following is the cost of quality classification for costs such as defects that pass through the system (e.g., customer warranty replacements, loss of customer or goodwill, handling complaints, and product repair)?
A) Appraisal costs
B) Prevention costs
C) External failure costs
D) Customer return cost
E) Workmanship costs

Accepted Answer

External failure costs refer to costs incurred due to defects that pass through the system and are discovered by customers. This includes costs such as customer warranty replacements, loss of customer or goodwill, handling complaints, and product repair. Appraisal costs refer to costs incurred to ensure that products or services meet quality standards, while prevention costs refer to costs incurred to prevent defects from occurring in the first place. Customer return cost and workmanship costs are not recognized cost of quality classifications.

Question 9

DPMO refers to
A) defects per million parts.
B) defects per many units.
C) defects per million operations.
D) defects per million opportunities.
E) defects per million.

Accepted Answer

DPMO stands for defects per million opportunities, which is a measure of process performance that calculates the number of defects that can be expected per million units produced or opportunities for error in a process.

Question 10

Which of the following is a dimension of design quality?
A) Price
B) Features
C) Color
D) Weight
E) Quality at the source

Accepted Answer

Features are a dimension of design quality. Price, color, weight, and quality at the source are not dimensions of design quality.
