Document the cause and close the case

Recommend disciplinary action for the operator

Guide the team to reframe the cause into a system-level issue

Skip to FMEA to assess recurrence risk

Increase end-product inspection frequency

Retrain all operators regardless of involvement

Implement a poke-yoke (error-proofing) device that addresses the actual root cause

Fault Tree Analysis (FTA)

Pareto Chart

Answer explanation

Justification: Is/Is Not helps define the boundaries of the problem clearly by comparing what it is and what it is not.

FMEA is corrective; RCA is preventive

FMEA occurs after a failure; RCA occurs before a failure

FMEA is a proactive risk assessment tool; RCA is a reactive investigative tool

FMEA and RCA are interchangeable within CAPA

Answer explanation

Justification: FMEA is proactive and used in design or planning stages; RCA is used after a problem has occurred.

MULTIPLE CHOICE QUESTION

When using Is/Is Not analysis, which of the following represents a flawed approach to defining what the problem is not?

Saying "It is not affecting Machine B" when Machine B is unrelated to the process

Saying "It is not occurring during night shift" while evidence shows 24/7 occurrence

Saying "It is not part of the new process" without historical context

Saying "It is not caused by Operator A" because Operator A was on leave

Answer explanation

Justification: The 'Is Not' category should involve relevant contrasts; Machine B is irrelevant and misleading.
