CPP Process Analysis & Improvement Techniques 2

Question 1

Which technique uses a structured diagram to identify all possible causes of a problem by grouping them into major categories such as people, process, equipment, and environment?

Accepted Answer

Fishbone (Ishikawa) diagram

Answer

The fishbone (Ishikawa) diagram organizes potential causes into major categories to systematically trace the root cause of a problem.

Question 2

In process improvement, the 'voice of the customer' (VOC) is primarily used to:

Accepted Answer

Identify and prioritize customer requirements

Answer

VOC captures customer needs and expectations so that process improvements are aligned with what customers actually value.

Question 3

A process map that includes both the process steps and the departments or roles responsible for each step is called a:

Accepted Answer

Swim lane diagram

Answer

Swim lane diagrams display process steps within horizontal or vertical lanes assigned to specific roles or departments, showing accountability.

Question 4

Which statistical concept measures the extent to which a process consistently meets specification limits relative to its natural variation?

Accepted Answer

Process capability (Cp/Cpk)

Answer

Process capability indices (Cp, Cpk) compare the spread of process output to specification limits to determine whether the process can reliably produce conforming output.

Question 5

In a DMAIC project, during which phase would a team most likely conduct a Measurement System Analysis (MSA)?

Accepted Answer

Measure

Answer

MSA is conducted in the Measure phase to validate that the measurement system is accurate and reliable before collecting process data.
