45. A successful root-cause analysis (RCA) should:

Answer: A

Explanation:

A successful root-cause analysis (RCA) should focus primarily on systems and processes.

Effective root-cause analysis emphasizes the examination of systems and processes to identify underlying issues that contribute to problems. By focusing on these areas, organizations can implement meaningful changes to prevent future occurrences.

A) focus primarily on systems and processes.

This option is correct because a successful RCA involves understanding how various systems and processes interact and contribute to issues. By analyzing these components, organizations can identify the root causes of problems rather than just addressing symptoms.

B) assume adherence to policies and procedures.

This option is incorrect as an RCA should not assume adherence to existing policies and procedures. Instead, it must investigate whether these guidelines are being followed and if they are effective in preventing issues.

C) neglect to identify deep-seated, latent failures.

This option is incorrect because a thorough RCA must include the identification of deep-seated, latent failures. Ignoring these factors can lead to incomplete analyses and the potential for recurring problems.

D) avoid including a sequence of events.

This option is incorrect as understanding the sequence of events leading to an incident is crucial in RCA. Mapping out these events helps to illuminate how and why failures occur, enabling better prevention strategies.

Conclusion

The focus of a successful root-cause analysis on systems and processes is essential for uncovering the true origins of issues. All other options fail because they either limit the scope of the analysis or overlook critical components that could lead to a more comprehensive understanding of the problems at hand. By prioritizing systems and processes, organizations can achieve more effective and sustainable solutions.
