Root Cause Analysis

Term from Mechanical Maintenance industry explained for recruiters

Root Cause Analysis is a systematic method used in maintenance and repair to find out why equipment or processes fail. Think of it like being a detective - instead of just fixing what's broken, maintenance professionals dig deeper to understand what actually caused the problem to prevent it from happening again. It's similar to how a doctor doesn't just treat symptoms but tries to find out what's causing an illness. This approach helps companies save money by preventing repeated breakdowns and improving equipment reliability.

Example Interview Questions

Senior Level Questions

Q: Can you describe a complex equipment failure where you led a Root Cause Analysis and what was the outcome?

Expected Answer: Look for answers that show leadership in organizing the investigation, involving different departments, using data to support findings, and implementing lasting solutions that prevented similar failures.

Q: How do you determine if a Root Cause Analysis is needed for an equipment failure?

Expected Answer: Should explain how they assess the severity and frequency of problems, consider business impact, and balance resources required against potential benefits.

Mid Level Questions

Q: What tools or methods do you use in Root Cause Analysis?

Expected Answer: Should mention common techniques like 5-Why Analysis, Fishbone Diagrams, or similar problem-solving tools, with examples of how they've used them.

Q: How do you document your Root Cause Analysis findings?

Expected Answer: Should describe creating clear reports with evidence, recommendations, and action plans that others can understand and follow.

Junior Level Questions

Q: What is Root Cause Analysis and why is it important?

Expected Answer: Should explain that it's a method to find the true source of problems, not just fix symptoms, and how it helps prevent repeated failures.

Q: What's the difference between a symptom and a root cause?

Expected Answer: Should be able to explain that symptoms are visible problems (like a machine stopping), while root causes are the underlying reasons (like lack of maintenance or wrong operating procedures).
