CSIP Level 1 Troubleshooting: Known Symptoms, Causes, and Corrective Actions
Verifying
Corrective
Actions
Once the system fault has been identified and you have performed (authorized) corrective
actions to repair the failure, conduct whatever tests are necessary to ensure that the problem is
fixed and that the system meets its optimum level of performance. Typically, it will be the same
testing that led you to isolating the cause of the specific problem (refer to your notes) and then
additional tests that give you confidence that the system is generally performing as it should.
Returning the
System to
Service
Once the reported problem is fixed and the system tests are successful, return the system to the
customer and close the call:
• Formally document the problem and the solution: Write down exactly what problems you
discovered and what corrections you made.
• Provide feedback: Communicate to all affected parties what problems you discovered, how
you arrived at that conclusion, and what corrections you made. Include this information with
parts that are returned for repair and, if appropriate, send e-mail with this information to ISS
personnel who could find it useful.
