Table 1-1: Troubleshooting Methodology
What to Check
Troubleshooting Method
What are the results of each
troubleshooting step?
Look for and record new
symptoms, such as error
messages or informational
messages.
Were the results logical,
consistent, and expected?
Did anything change? If so, what?
Check system logs. Look for any
type of change, no matter how
insignificant.
Was any functionality gained or
diminished?
Look for functionality changes to
judge the effectiveness of each
troubleshooting step.
Were any errors made in
implementing a step?
Look for and record any mistakes
made while executing a step.
Was more than one variable changed
at a time?
To be sure that the specific cause
of the problem is isolated, be sure
that during each step only one
variable is changed at a time.
Were any steps skipped or completed
out of order?
Place checkmarks against the
steps as they are executed, and
circle the steps not executed. Look
for skipped steps or steps
executed out of order.
Were any steps accidentally added?
Were any steps added intentionally to
complete or correct another step?
If steps had to be added in order
to proceed, record why, and note
the preceding step.
