Defect Elimination
Defect elimination is the structured removal of recurring equipment defects and the conditions that create them.
What this term means in maintenance
Defect elimination is the structured removal of recurring equipment defects and the conditions that create them.
Sources of defects
Defects may originate from:
- Design
- Installation
- Operation
- Lubrication
- Contamination
- Maintenance practice
- Materials
- Environment
- Procedures
- Supplier quality
Practical example
Repeated bearing failures are eliminated by correcting alignment, improving sealing, changing lubrication practice, and adding installation verification.
Defect-elimination process
A practical process may include:
- Identify recurring defects
- Rank impact
- Investigate causes
- Define permanent actions
- Assign ownership
- Implement
- Verify effectiveness
- Standardize learning
Data sources
Use bad-actor lists, Pareto analysis, repeat failures, downtime, costs, inspections, and operator reports.
Common mistake
Replacing the failed component without addressing the condition that caused it is repair, not defect elimination.

Root Cause Analysis
Root cause analysis is a structured investigation used to identify the underlying conditions that allowed a failure or problem to occur and determine actions that reduce recurrence.
Bad Actor Asset
A bad actor asset is equipment that repeatedly creates disproportionate failure, downtime, maintenance cost, safety risk, or operational disruption.
Equipment Reliability
Equipment reliability is the probability that an asset will perform its required function without failure for a defined time under stated operating conditions.
Glossary FAQs
- What is defect elimination?
The structured removal of recurring equipment defects and their underlying conditions.
- How is it different from repair?
Repair restores function; defect elimination prevents recurrence.
- What data supports defect elimination?
Repeat failures, Pareto, bad actors, downtime, costs, inspections, and root cause evidence.
