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:

  1. Identify recurring defects
  2. Rank impact
  3. Investigate causes
  4. Define permanent actions
  5. Assign ownership
  6. Implement
  7. Verify effectiveness
  8. 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.

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.
