Actually, a buddy of mine switched to a similar setup last year and his shop's productivity shot up. He used to be all about wrenching but now he handles the intake calls and diagnostics, which let him spot a recurring issue with a specific model that was eating up hours in the bay. @christopher943 mentioned improved turnaround, and isn't that exactly what we're after here? Why cling to the idea that grease under the nails is the only measure of worth when the whole shop runs smoother? My friend says he actually gets to dig into the real head-scratchers now instead of being buried in routine checks.
