Hours per RO is unfortunately only a "partial" measurement and NOT a very good one at that. I realize that this whole industry adpoted it as "acceptable" and it was probably some yahoo like me (Consultants) who started this fiasco in an effort to sell a dealer his services.
Although, I can go and have gone on a lot longer than I should here to explain why this is such a poor measurement - let me give you some highlights.
First and foremost, whether you "normalize" by performing some arbitrary math to allow urban and rural dealerships to compare to each other, the act of dividing by an equally arbitrary door rate makes no sense. This "math" implies that the door rates in the respective rural and urban markets generate the exact same gross profit. If they do generate the exact same gross profit, it is at least a little bit closer to a fair comparison, but the likelihood of that exactness is slim to none, therefore, the "divider" is, for all intent and purpose - irrelevant.
The second point and clearly the most important one is the actual flat rate times from one location to the next. If you could confidently say that every service operation utilized the exact same Flat Rate times for each maintenance service or repair service, at least the hours could be equally compared, but as you all know - that is simply not the case. I've been to dealerships who pay techs 0.2 for LOF's and others who pay 0.5, one who pays 0.4 for a 4-Wheel aligment and another who pays 2.0, tire rotations that vary from 0.2 to 1.0, brake jobs that vary from .5 to 2.5 - should I go on??
Even if two operations were "selling" the same amount (volume) of these services, the hrs/ro would be different implying that one (the higher) is better than other - That really is somewhat inaccurate dont you think?
If the flat rate hours are different, in order to still "TRY" to compare the two, it would mean that the labor sale amounts of each of these services would have to be exactly equally proportionate to the other. So an Alignment with a FRH of 0.4 would have to sell for $40 and the other service operation would have to sell their 2.0 Aligment for $200 to equally compare these two. Honestly - if one market dictates competitively that an alignment sells for $200 and another market dictates competitively to sell it at $40 - please share with me and the rest of the visitors to this forum which two markets are that aligned (no pun intended) as it simply doesnt exist. Furthermore, a market with $200 alignments most likely has different technician costs than a market with $40 alignments so measuring "sales amounts" be that hours or labor dollars is an act in futility.
Gross profit will be the true difference in the two sample markets, and measuring that will at least allow comparisons to be accurate, but measuring CP only is only "partially" measuring your shop.
In all reality though, hours per RO was developed as a means to measure whether or not an operation was maximizing the opportunities coming into the service lanes, and the only true measurement of whether or not an opportunity was maximized is to have consisent "opportunity" measurements, which has never been explored by the industry.
EXAMPLE:
Dealer X maintenance menu lists a 30K service as 1.0 hr and $129.95, and that same dealers window of "opportunity" is +/- 1500 miles and has a "penetration" of 80%.
Dealer Y maintenance menu list a 30K service as 4.0 hrs and $599.95 a +/- window of 2500 miles and has a penetration of 50%.
Which service operation is doing a better job?
Remember - YOUR SHOP has CP/WP/IP every single day, and it all generates gross and ideally net profit. Dont't lose sight of the bottom line on your way to it. Measuring CP only is like a showroom only measuring one of the models they sell, rather than ALL of the vehicles sell. All of the pay types combine to a total, and its the total that we take to the bank.
I can ramble on even more as needed, but I will end this post with this:
Don't let supposed "experts" (of which I realize I am one of) make blanket statements as to what is the "proper" number, the proper RO Count, the proper measurement, the proper gross, the proper sale - every measurement has merit and the totals are driven by each collectively not individually.
As one of those guys who is great with the numbers myself, I can prove or disprove just about anything with data - what you really need to determine is whether or not you are moving forward (improving) or moving backward and if you need help with that - get the help!
