Bobby Petitt shows how scheduling a fixed number of appointments per time slot creates hidden chaos in auto shops. Four cars every 15 minutes with 45-minute service slots sounds manageable, but early arrivals leave technicians idle and upsells extend each job, pushing later appointments into overload and crushing customer wait times and satisfaction.
Counting cars is broken and your customers are suffering. Here's why. Let's say you've got 12 Express technicians. No carryovers, everyone starts fresh, 7 AM. Your schedule? 4 appointments every 15 minutes, one per each advisor. Sounds organized. It's actually a bomb in disguise. 7 AM, 4 cars show up. 4 technicians to work on them. 8 techs standing around equals about 2 hours of spoiled time. 4 more at 7:15, still not full. And then, you know, 7:30, we're finally all working. Here's where you get trapped. Those first inspections, they're already done. Advisors are upselling, customers are saying yes, everything feels good. This is about the time that bomb goes off. Well, why is that? It starts with your advisors selling things. These additional items take additional time, and you only allotted 45 minutes for each appointment. 45 minutes each appointment plus those upsells, that's more time per car. And so now those 16 cars coming in at 9 AM, at 10 AM, at 11 AM, even if you only sell one or two things on a handful of them, so you're overloaded. Customers wait longer, buy less, and give you a bomb of a survey to top it off. So the natural follow-up question is, how do I stop counting carts? I am so glad you asked.
