Root Cause Analysis

A.

A root cause analysis is a systematic process of identifying the underlying cause of a problem or issue that has occurred. It involves a detailed examination of the problem and its symptoms, in order to determine the underlying factors that led to the issue. The main purpose of conducting a root cause analysis is to prevent the same problem from recurring in the future.

The answer that best describes a root cause analysis is (A) Identify the circumstances that initiated the problem. This is because the first step in a root cause analysis is to identify the initial cause or trigger of the problem. This involves understanding the sequence of events that led to the issue, and examining the context in which the problem occurred.

Once the circumstances that initiated the problem have been identified, the next step is to replicate the problem in a test environment, as described in option (B). This involves recreating the conditions that led to the problem, in order to better understand its root causes.

After the problem has been replicated, the next step is to confirm the theory of probable cause, as described in option (D). This involves testing various hypotheses to determine which factors were responsible for the issue.

Finally, once the root cause of the problem has been identified, the necessary corrective actions can be taken, as described in option (C). This involves implementing solutions to address the underlying causes of the issue, in order to prevent it from recurring in the future.

In summary, a root cause analysis involves the following steps:

1. Identify the circumstances that initiated the problem.
2. Replicate the problem in a test environment.
3. Confirm the theory of probable cause.
4. List necessary corrective actions for the problem.
