Shop Operations and Business Management
How the day makes money
Shop operations questions test whether you understand where profit is created and where it leaks.
The repair order is the spine of the business: customer concern, cause, correction, parts, labor, approvals, and documentation. Warranty claims, comeback analysis, and customer disputes all depend on the RO being complete and legible. Dispatch and scheduling decide whether capacity matches demand; overbooking creates waits, and a long wait is one of the most common causes of a poor survey.
Learn the money math. Labor sales come from flag (flat-rate) hours sold at a labor rate. Effective labor rate is total labor sales divided by total flag hours sold, so discounts and menu pricing show up there rather than in the posted rate. Parts carry a markup, often applied on a sliding matrix by price range. Productivity and efficiency describe how much of a technician's paid time converts into billable flag hours; when you schedule poorly, technicians stand around while the shop pays for hours it cannot bill. A comeback consumes the original labor, replacement parts, and a bay that could have sold other work, so it costs far more than the profit on the original job.
Track the numbers you can influence: car count, average repair order, hours per RO, comeback rate, and customer satisfaction index. Know the basics of compliance too - safe handling and disposal of fluids and used parts, and accurate records for warranty and tax.
Trap: confusing hours sold with hours worked, or quoting the posted labor rate when the question is about effective labor rate. Also watch for answers that boost this week's sales by promising capacity the shop does not have.
Rule of thumb: a repair order should be complete enough that a stranger could pick it up a year later and explain exactly what was sold, approved, and declined.
