RCA RCA Corrective Actions

Question 1

In RCA, what distinguishes a 'corrective action' from a 'containment action'?

Accepted Answer

Corrective actions address the root cause to prevent recurrence; containment actions provide immediate short-term relief

Answer

Containment actions are temporary fixes to stop immediate harm, while corrective actions target the root cause to permanently prevent the problem from recurring.

Question 2

Which of the following is an example of a 'systemic corrective action' in RCA?

Accepted Answer

Redesigning the process to prevent the error from being possible regardless of who performs it

Answer

Systemic corrective actions change the system or process so that the root cause condition cannot recur, rather than just addressing the individual incident.

Question 3

What is the 'hierarchy of corrective actions' in RCA, ranked from most to least effective?

Accepted Answer

Elimination → Engineering controls → Administrative controls → Training

Answer

Elimination of the hazard is most effective; then engineering controls; then administrative controls; and lastly training, which is least reliable for preventing recurrence.

Question 4

In RCA, what does it mean to 'mistake-proof' (poka-yoke) a process as a corrective action?

Accepted Answer

Designing the process so that errors are impossible or immediately obvious

Answer

Mistake-proofing (poka-yoke) redesigns a process or tool so that an error either cannot be made or is instantly detected before it causes harm.

Question 5

Why is it important to assign a specific owner and due date to each corrective action in RCA?

Accepted Answer

To ensure accountability and track progress toward timely implementation

Answer

Assigning ownership and due dates creates accountability, ensures actions are not forgotten, and allows progress to be monitored until completion.
