How do you really know? Here’s a simple way to get a pretty good idea. Spend some time doing a little investigating to get a reasonably good idea of the sales at other shops in your area. Then take the total number of techs and service advisors (added together) at each shop and divide it into their sales. Now, compare the findings to the number at your shop. Odds are that you will find a very wide range of results and get a fairly good handle on how your shop measures up. Too many or too few employees will prevent you from maximizing your potential, something that is especially critical in a tough economy.
