Question

match each characteristic to the corresponding approach to performance measurement.

more than one characteristic will match to each approach.

a works with discrete data
b used for continuous data that has normal distribution
c examines conformity of process outputs
d compares process variability or standard deviation to specification limits
e used to calculate dpu or dpmo

measuring variability
counting defects

Explanation:

Analyze performance measurement approaches

In Six Sigma Metrics, performance measurement is broadly categorized into two main approaches: "Measuring variability" (continuous/variable data) and "Counting defects" (discrete/attribute data).

Classify characteristics for measuring variability

Measuring variability focuses on continuous data, distributions, and comparing process variation (like standard deviation) to specifications:

• B (Used for continuous data that has normal distribution) directly relates to continuous measurements.
• D (Compares process variability or standard deviation to specification limits) is a core method for assessing process capability using variability.

Classify characteristics for counting defects

Counting defects focuses on discrete data, counting occurrences of nonconformities, and calculating defect-based metrics:

• A (Works with discrete data) describes attribute data where we count occurrences.
• C (Examines conformity of process outputs) determines whether an item is defective or nonconforming.
• E (Used to calculate DPU or DPMO) utilizes DPU Calculation and DPMO Study metrics, which are based on counting defects.

Answer:

• Measuring variability: B, D
• Counting defects: A, C, E
