Predictive Maintenance
Predictive Maintenance is a modern approach to keeping machines and equipment healthy. Instead of waiting for things to break or doing routine checkups on a fixed schedule, it uses various tools and sensors to spot potential problems before they happen. Think of it like a doctor who monitors vital signs to prevent illness, rather than treating sick patients. This approach helps companies save money by avoiding unexpected breakdowns and unnecessary maintenance work. Similar terms include "condition-based maintenance" or "preventive maintenance," though predictive maintenance is more advanced because it uses data and monitoring tools to make smart decisions about when maintenance is actually needed.

Example Interview Questions
Senior Level Questions
Q: How would you implement a predictive maintenance program in a facility that currently uses reactive maintenance?
Expected Answer: Should discuss step-by-step approach including equipment assessment, sensor deployment, data collection methods, staff training needs, and ROI calculations. Should emphasize change management and getting buy-in from stakeholders.
Q: How do you determine the cost-effectiveness of a predictive maintenance program?
Expected Answer: Should explain comparing costs of implementation against savings from reduced downtime, fewer emergency repairs, extended equipment life, and improved productivity. Should mention tracking key performance indicators (KPIs) and calculating return on investment.
Mid Level Questions
Q: What are the main tools and techniques used in predictive maintenance?
Expected Answer: Should mention common monitoring tools like vibration analysis, thermal imaging, oil analysis, and equipment sensors. Should explain basic purposes of each and when they're typically used.
Q: How do you prioritize maintenance tasks based on predictive data?
Expected Answer: Should explain how to assess equipment criticality, interpret warning signs, and balance urgent needs with scheduled maintenance. Should mention resource allocation and planning.
Junior Level Questions
Q: What's the difference between predictive maintenance and preventive maintenance?
Expected Answer: Should explain that preventive maintenance is done on a schedule regardless of condition, while predictive maintenance uses actual equipment condition data to determine when maintenance is needed.
Q: What are some basic signs that equipment might need maintenance?
Expected Answer: Should mention obvious indicators like unusual noises, vibrations, temperature changes, or decreased performance. Should show understanding of basic monitoring techniques.
