Testing



 

 


After taking some overt repair action the repair should be tested. This usually means performing the task that failed in the first place.

If the repair action has not been successful, you should begin the procedure over again starting with the observed symptoms. It is possible that they have changed due to the action you have taken and you need to be aware of this in order to make informed decisions during the next iteration of the process. Even if the problem has not been resolved the altered symptom could be very valuable in determining how to proceed.
