Maybe you've got a couple mechanics who can bang out big jobs and some that can hammer through brakes and ball joints. Also maybe none of them are exactly competent with a volt meter or schematics. Not putting anyone down, but that is a very common scenario.
So instead of taking a productive mechanic off of a profitable job and throwing him in over his head on a missing 5v reference or tricky misfire, you call in the diag guy.
If you're floating in gravy, you probably don't need a guy like that on the pay roll, and you can bill the customer for the diagnosis so his fee doesn't come out of pocket.
No matter how good your guys one reason is a good specialist dignostician will not only have the specialst tools to get a handle on the fault, but has built up a working knowledge of how manufacture X has changed the systems on model Y and likely common faults.
The trade always has used specialist of one kind or another for 100 years, back in my grandads day he would get a specialist to rewind a magneto or re-metal a bottom end, sub-contracting to a diagnostic guy isn't any different, you will probably still do 99% of diagnosis in house but for that 1% that is a time burning pita call the man.
It is a subject Paul has covered many times.

How would one go about convincing a garage owner that to use a diagnostician. What would be the best scanner (not brand ) for a stat up diagnostician to use.
Thank you for the answers to my previous question
