Which problem-solving method is commonly used in maintenance to identify root causes?

• A. Failure Mode and Effect Analysis (FMEA) approach.
• B. Root Cause Analysis (RCA), often using the 5 Whys or fishbone diagram.
• C. Preventive Maintenance Analysis (PMA) technique.
• D. Corrective Action Evaluation (CAE) method.

Answer: (D)

Root cause analysis is the go-to method for identifying the underlying reason a problem occurred in maintenance. By digging beyond symptoms, it helps teams prevent recurrence rather than just fixing the immediate issue. Techniques like the 5 Whys push you to keep asking why until you reach a fundamental cause, while a fishbone diagram (Ishikawa) organizes potential causes into categories such as equipment, process, people, materials, and environment. This structured thinking makes it clearer where to apply effective corrective actions. FMEA is a proactive tool that assesses potential failure modes and their effects before they happen, prioritizing improvements; it guides prevention but isn’t the primary method used to pinpoint a root cause after a problem occurs. Preventive Maintenance Analysis isn’t a standard, widely used term for root-cause work, and Corrective Action Evaluation focuses on evaluating actions rather than discovering the original cause.
