In North America today, the average key-to-key repair time is between 8 and 10 days.
This means that from the moment the customer leaves the vehicle at the body shop until the vehicle is returned, more than a week typically passes.
However, when we analyze the repair process more closely, something surprising appears.
A typical collision repair requires between 16 and 20 hours of actual labor.
In other words, the car only receives about two days of real work.
If we subtract the average time required to receive spare parts — typically around two days and outside the body shop’s control — the internal repair process still takes approximately six to eight days.
This raises a fundamental question:
Why does a repair that requires two days of work take six to eight days to complete?
The real problem: waiting
The answer lies in how most body shops are organized.
Traditional body shops are structured around independent departments:
- Disassembly
- Body repair
- Preparation
- Painting
- Reassembly
Each department works to maximize its own productivity.
However, this departmental structure creates a hidden problem:
vehicles spend more time waiting between operations than actually being repaired.
A car may wait:
- for the body repair technician
- for a preparation bay
- for the paint booth
- for reassembly
While technicians remain busy within their departments, the overall repair process becomes slow and unpredictable.
The metric that reveals the problem
In manufacturing industries, this inefficiency is measured using a concept called Touch Time.
Touch Time measures how long the product actually receives work.
In collision repair, the difference between total repair time and touch time is often dramatic.
A vehicle may remain in the shop for 8 to 10 days, but receive only 16 to 20 hours of real work.
This means that the majority of the repair time is not spent repairing the vehicle.
It is spent waiting.
The industrial perspective
Modern production systems solved this problem decades ago by focusing on flow instead of departments.
The objective is not to keep each department busy.
The objective is to keep the product moving continuously through the process.
When repair operations are synchronized and organized around flow, several things happen:
- waiting time disappears
- lead time collapses
- daily output becomes predictable
- capacity increases without adding resources
This is the difference between a traditional workshop and an industrial body shop.
The real challenge for modern body shops is not working faster.
It is eliminating the waiting between operations.
