Question 1

In Six Sigma methodology, the DMAIC improvement cycle stands for:

Accepted Answer

Define, Measure, Analyze, Improve, Control

Answer

Design, Measure, Analyze, Improve, Control

Answer

Define, Monitor, Assess, Integrate, Complete

Answer

Design, Model, Analyze, Implement, Check

Question 2

A process operating at Six Sigma quality level produces approximately how many defects per million opportunities (DPMO)?

Accepted Answer

3.4

Answer

66,807

Answer

233

Answer

6,210

Question 3

The process capability index Cp is calculated using which formula?

Accepted Answer

(USL − LSL) / 6σ

Answer

(Mean − LSL) / 3σ

Answer

(USL − Mean) / 3σ

Answer

(USL + LSL) / (2 × Mean)

Question 4

In statistical process control (SPC), a p-chart is used to monitor:

Accepted Answer

The proportion of nonconforming (defective) items in successive samples

Answer

The average value of a continuous quality characteristic within subgroups

Answer

The range of measurements within each sample subgroup

Answer

The total number of defects per unit of product

Question 5

Acceptance sampling is a quality technique used primarily to:

Accepted Answer

Decide whether to accept or reject an entire lot based on inspection of a random sample

Answer

Control quality during active production by adjusting process parameters

Answer

Inspect every single item in a shipment to guarantee 100% conformance

Answer

Train operators to reduce defect rates through skill development

Question 6

In a Pareto analysis applied to quality improvement, the '80-20 rule' implies that:

Accepted Answer

Approximately 20% of defect types (vital few) account for roughly 80% of quality failures

Answer

80% of quality problems are caused by all factors equally

Answer

80% of products generate only 20% of total revenue

Answer

Eliminating 20% of workers will reduce 80% of defects

Question 7

In Failure Mode and Effects Analysis (FMEA), the Risk Priority Number (RPN) is calculated as:

Accepted Answer

Severity × Occurrence × Detection

Answer

Frequency × Impact × Probability

Answer

Severity + Occurrence + Detection

Answer

(Severity × Occurrence) / Detection
