🔍 Key Concepts

• Difference between preventive, predictive, and run-to-failure maintenance strategies • What trend analysis means in the context of equipment condition (vibration, temperature, oil analysis, hours of operation, etc.) • How planned maintenance is usually scheduled (time-based or usage-based) versus condition-based

💭 Think About

• Ask yourself: when you perform trend analysis on data (like vibration readings over months), are you trying to react after failure, prevent on a fixed schedule, or anticipate when a failure is likely to occur? • Consider which option relies most heavily on data patterns over time to decide when to do the maintenance, instead of using just a calendar or running the equipment until it breaks. • Think about which scheme would benefit most from graphs, logs, and monitoring systems that show gradual changes in equipment condition.

✅ Before You Answer

• Identify which option is primarily condition-based, using actual equipment condition and data trends, not just time or running-to-break. • Eliminate any option where maintenance is done only after failure or strictly on a fixed time interval with no need for detailed data analysis. • Match the term that is commonly paired with techniques like vibration analysis, oil analysis, temperature trending, and performance monitoring.
