Two Lenses, One Customer
What audits and mystery shopping each see in the car dealership, what each one misses, and how the best-run networks use both.
- Audits check that the standard is in place. Mystery shops check that it reaches the customer.
- Each has blind spots the other covers: audits see the facility, equipment and records; shops see behaviour on an ordinary day.
- When the two disagree, the disagreement is the finding, and each kind of disagreement needs a different fix.
- The best-run networks connect them: one standard, two lenses, one action loop.
