Paradox:

1. It’s broken because we did not work on it

2. It’s broken because we did work on it.

Education is critical to solving the reliability paradox. For instance, it’s broken because we didn’t know how to prevent it from breaking. Or it’s broken because we didn’t know it was breaking and therefore didn’t work on it. Or this, it’s broken because we didn’t know it wasn’t breaking and worked on it anyway. Or simply, we didn’t know how working on it might cause it to break.

Maintainability is typically defined as the ease, economy, safety and accuracy with which the necessary maintenance of a machine can be effectively undertaken. When machines are designed and built for optimized maintainability, many benefits are realized including:
 

• Increased reliability

• Lower overall costs of enabling reliability

• Decreased time to complete maintenance tasks

• Fewer maintenance errors

• Reduced maintenance injuries

• Less training required to perform tasks

• Improved troubleshooting effectiveness
