Troubleshooting

SPU

s is

the

process of

getting

answers

to

these

five

questions:

•

What

exactly

is

wrong,

or

what

are

the

bad

symptoms?

• Where

are

the

bad

symptoms

appearing?

•

When

do

the

bad

symptoms

occur?

• How

bad

is

the

problem

or

to

what

extent

does it occur?

•

What

actually

caused

the

problem

in

the

first place?

Getting

the

answers

to

these questions usually makes

the

troubleshoot-

ing

process much more effective

and

less costly. \Vhen a failure in a

workstation

occurs.

remember

these

questions

and

get

the

answers

to

each of

them.

After

you have all answers possible, decide

what's

the

most

probable

cause of

the

problem. Sometimes you'll arrive

at

several choices for a

cause.

For

each choice, qualify it against

the

answers

to

the

questions

above.

The

most

probable

cause is

the

one

that

logically justifies

the

correct answers

to

these

questions.
