RCA Problem Definition Flashcards

In RCA, what is a 'triggering event'?

Answer: The immediate event that directly caused the problem to occur

A triggering event is the proximate or immediate cause that directly set the problem in motion, as distinguished from the deeper root cause.

Why is 'problem containment' considered a separate step from 'root cause identification' in RCA?

Answer: Containment stops immediate harm while the deeper cause is still being investigated

Containment actions are short-term measures to limit immediate damage or recurrence while the full RCA investigation determines and addresses the true root cause.

What does a 'problem recurrence' after a corrective action suggest about the original RCA?

Answer: The true root cause was not identified or addressed

If a problem recurs after a corrective action, it typically means the RCA addressed a symptom or contributing cause rather than the true root cause.

In RCA problem definition, what does 'extent of condition' mean?

Answer: Checking whether similar problems exist in other related products, processes, or systems

Extent of condition analysis asks whether the same root cause may be affecting other areas beyond the initial problem, to prevent wider failures.

What is the difference between a 'proximate cause' and a 'root cause' in RCA?

Answer: A proximate cause is the immediate cause of the event; a root cause is the fundamental systemic reason behind it

A proximate cause is the direct, immediate cause of the event, while the root cause is the deeper systemic or latent reason that, if fixed, prevents recurrence.

In RCA, when should investigators use 'operational definitions' for problem terms?

Answer: At the start, to ensure all team members interpret key terms consistently

Operational definitions ensure that all investigators interpret key terms (like 'defect' or 'failure') in exactly the same way, preventing miscommunication during data collection.
