I ran lateral support groups for 15 years and installed them in 5 dealerships in our dealer group - You can generate 120% efficiency and high work quality because of the personal accountability (techs to advisors).
I agree with Gene's metrics.
*Shoot for about 20 r.o.s per day, 2.5 hrs per r.o. and +100% efficiency per tech per day - 5 techs per advisor with a skill mix across all levels of work (lube tech through master for each group in order to average your labor cost per hour down) (helps control labor gross at +72%).
The Service Manager must be an active agent in his environment - driving the shop toward profitability hour by hour - he is on the drive early and stays late to review R.O.s and compile the daily metrics. Without that discipline the process is doomed.
Advisors make reservations, write service , sell, dispatch, make customer follow-up calls and are responsible for the daily CSI and profitability metrics of their group. NO CASHIERING!!!! Selling skills do not necessarily translate into good clerical skills - just ask the office manager in a dealership with advisor/cashiers - after her daily journal entries to correct advisor mistakes.
Tech metrics are tracked daily also - Techs are responsible for up-selling 2 hours of their time daily.
Those are simple guides that can be used to DRIVE the shop toward profitability. But the question is really a total systems question. Without a good shop loading and scheduling system, running an efficient and productive shop is a crap shoot. The DMS systems are very expensive and are too complicated for most shops to use effectively(given advisor turn-over/training requirements). Turn it off if you have it and save $6000 a year. There are other PC based reservation systems that are easy to use, 1/10th the cost, allow advisors to schedule and load their groups daily - based on management objective metrics for total hours, work mix, and tech skill. That same system will also accommodate a first come /first serve system in tandem with reservations (hello quick lube!).
The other issue revolves around how you now handle that knowledge of your future customer flow. That means running service history on everyone and planning the service visit to maximize the selling opportunities in the drive (lane processes are key to good CSI and good sales)that are worth an extra .3 per hrs.R.O.
The next most critical piece of the pie - lets make the pie even bigger - is a very disciplined MPI process and a professional sales presentation when additional service is found (+.5hrs. per R.O.). Most advisors talk themselves out of the bulk of additional sales (too much information and too disorganized).
Good luck - managing service is a full time job and demands a strong leader that has a vision of what he wants. He is willing to constantly follow the "road signs" and remove "barriers" on the way to his destination.
