What metric is often used to track equipment failures in TPM?

• A. Mean Time Between Failures (MTBF)
• B. Overall Equipment Efficiency (OEE)
• C. Return on Investment (ROI)
• D. First Pass Yield (FPY)

Answer: (A)

The metric commonly used to track equipment failures in Total Productive Maintenance (TPM) is Mean Time Between Failures (MTBF). MTBF measures the average time that equipment operates before experiencing a failure, which is crucial for understanding the reliability of machinery and identifying patterns in breakdowns. By assessing MTBF, organizations can pinpoint when equipment is most likely to fail and work on preventive measures to reduce downtime. This emphasis on reliability aligns with the overarching goals of TPM, which focuses on maximizing equipment effectiveness by minimizing breakdowns and enhancing maintenance practices. While Overall Equipment Efficiency (OEE) is a vital metric that offers a broader viewpoint on how well manufacturing operations are performing, it encompasses more than just equipment failures—it also considers factors like availability, performance, and quality. Return on Investment (ROI) measures the financial return on investments but does not focus on equipment performance or maintenance. First Pass Yield (FPY) assesses product quality by measuring the percentage of products manufactured correctly without rework but does not relate directly to equipment failure tracking. Therefore, MTBF stands out as the most relevant metric for monitoring equipment failures in the context of TPM.
