CQIA Root Cause Analysis 5

Question 1

Which quality tool would BEST help a team visualize the sequence of steps in a process to identify where a defect-causing error could occur?

Accepted Answer

Flowchart/process map

Answer

A flowchart maps each process step and decision point, making it easy to identify where errors can be introduced.

Question 2

A team completes a root cause analysis and identifies the root cause as 'lack of defined standards.' The most appropriate corrective action is to:

Accepted Answer

Create and implement documented standards and verify employee understanding

Answer

Creating documented standards directly addresses the root cause of undefined expectations and provides a sustainable process control.

Question 3

In root cause analysis, 'error proofing' (poka-yoke) is considered effective because it:

Accepted Answer

Makes it physically impossible or immediately obvious when an error occurs

Answer

Poka-yoke devices prevent errors at the source or detect them instantly, eliminating the reliance on human attention to avoid mistakes.

Question 4

What does 'recurrence prevention' mean in the context of corrective action?

Accepted Answer

Taking action at the root cause level so the specific problem cannot happen again

Answer

Recurrence prevention means fixing the root cause so the identical failure mode cannot repeat, not just monitoring for its return.

Question 5

Which of the following situations would MOST warrant using a formal root cause analysis process?

Accepted Answer

A recurring customer complaint that has not been resolved despite multiple attempts

Answer

Recurring problems that resist resolution despite previous attempts are the strongest candidates for formal RCA, since superficial fixes have clearly failed.
