MTBF
MTBF (Mean Time Between Failures) is a key measure used in maintenance and reliability work to show how long equipment typically runs before it needs fixing. Think of it like a report card for machine reliability - the higher the MTBF number, the more reliable the equipment is. Maintenance teams use this to plan when to check and fix machines before they break down. It's similar to how we track mileage on cars to know when to do service, but for industrial equipment. When you see MTBF in resumes, it means the person has experience in tracking and improving equipment reliability.

Example Interview Questions
Senior Level Questions
Q: How would you implement an MTBF improvement program in a facility?
Expected Answer: Should explain how they would gather equipment data, analyze failure patterns, create maintenance schedules, train staff, and measure improvements over time. Should mention involving operators and maintenance staff in the process.
Q: How do you use MTBF data to make budget decisions?
Expected Answer: Should discuss how MTBF helps predict maintenance needs, plan equipment replacement, justify maintenance budgets, and calculate cost savings from reliability improvements.
Mid Level Questions
Q: How do you calculate MTBF and what factors affect it?
Expected Answer: Should explain that MTBF is total operating time divided by number of failures, and discuss factors like maintenance quality, operating conditions, and equipment age.
Q: What strategies have you used to improve MTBF?
Expected Answer: Should mention preventive maintenance, proper operator training, keeping good maintenance records, and identifying/fixing recurring problems.
Junior Level Questions
Q: What is MTBF and why is it important?
Expected Answer: Should explain that MTBF measures average time between equipment failures and helps predict when maintenance will be needed to prevent breakdowns.
Q: How do you track and record MTBF?
Expected Answer: Should discuss basic record-keeping of equipment runtime and failures, using maintenance software or spreadsheets, and the importance of accurate data collection.
