impact analysis
. take the failed parts and examine them to determine the cause of failure. inspect the parts to see if there has been some overload, excess wear or design flaw
Failure analysis
_____ you must look at why the failure occurred. if you can determine the root cuase of failure, take steps to improve the machines longevity so that the problem does not return
