When we talk to clients about poor
productivity in their service departments, they often respond by
telling us about how bad their technicians are and how they need
more of them. More of a bad thing? Go figure. Next we calculate
the number of total available service hours and determine that the
shop is selling less than 85% of its capacity. So much for being
understaffed! Now the client looks at us, like we’re crazy, and
says if I have so much extra time to sell, why are my customers
having to wait three weeks to get their cars in the shop? Well, we
reply, if you’re making your customers wait three weeks to get their
cars repaired, they’re not your customers anymore, they’re someone
else’s. At this point, the exasperated client asks again, so how
many more technicians do I need? We reply, don’t shoot the
technicians.True
story. Six months ago a prospective client calls. His shop is
operating at a loss, he can’t keep his customers happy, and the
technicians are crying because they aren’t making enough money.
Help! Today he is a client with a monthly increase in customer
paid gross of over 55%, a healthy bottom line in the shop,
satisfied customers, and better-paid employees. How many
technicians did he add? None. How many technicians did he
replace? None. What have we learned? Don’t shoot the technicians Service
departments are like assembly plants. Capacity is maximized when
combinations of systems are all working well in unison: engineering
systems, quality control systems, parts supply systems, sales
systems, production control systems, etc. When an assembly line is
operating at below capacity, it is rarely the fault of the
assembler. Like wise, when a service department is not producing
at capacity, it is rarely the fault of the technician. Uh? Why do
we believe this? We view a
service department as a collection of three operating systems:
management, selling, and production. If one system is broken, the
other two can’t operate efficiently and shop productivity falls.
When we survey a service operation for the first time, we typically
find a production system that can work, a management system that
doesn’t understand how it should work, and a selling system that
doesn’t exist.
There can be many different
culprits causing bottlenecks in shop production; here are a two of
the worst. Look at your appointment system and this is what you
might find.
Differing perceptions. To the service advisor an appointment
means drop your car off in the morning, and if we don’t screw up it
will be ready by this evening. To the customer, having an
appointment means I bring my car in at 8:15 am, I’m being charged
for one hour of work so it will be done, washed, and vacuumed, at
9:15. The problem here is that neither perception depicts
reality. The result is customer dissatisfaction.
Under booking. It is difficult to accurately predict
the flat rate hours needed to complete repairs without first
ascertaining the problem. Since most appointments are made over
the phone, an accurate diagnosis is usually impossible and the
estimated time for repair is a guess, normally too long rather than
too short. If the shop is loaded for the day based on its
appointments you can count on poor capacity utilization. In this same vein, appointment coordinators and service
advisors typically do not like irate customers at the end of a long
day, so to prevent such a likelihood they schedule less work rather
than more. This practice becomes a self-fulfilling prophecy for
diminishing sales and production. |
