What is the difference between preventive and corrective actions in CBM T6?

• A. Preventive actions stop issues from occurring; corrective actions fix issues after they occur.
• B. Preventive actions stop issues from occurring by addressing root causes; corrective actions fix issues after they occur.
• C. They are the same.
• D. Preventive actions are only used in safety contexts.

Answer: (A)

The main idea here is proactive versus reactive actions. Preventive actions are taken before a problem shows up, aiming to stop issues from occurring in the first place. In CBM T6 terms, this means analyzing how components might fail and implementing measures upfront—like adjusting maintenance schedules, improving processes, or adding monitoring so warning signs are caught early and failures are avoided.

Corrective actions, on the other hand, come after a problem has been detected. They focus on fixing the issue, restoring normal operation, and often include changes to prevent recurrence. So while preventive actions are about stopping failures before they happen, corrective actions address and repair failures after they occur.

The other options don’t fit because they either claim the actions are the same, limit preventive actions to safety contexts, or imply that preventive actions must address root causes in a way that the statement pictured here does not.
