In the workshop nobody answers the phone with greasy hands under a car. A call nobody picked up often does not come back. The driver simply calls the next garage in the search results.
Booked slots sit in a notebook or on someone’s phone. Customers call to ask whether the car is ready, mechanics stop work to answer, and whoever takes the cars in searches for who is booked when.
This is not a staff problem. What is missing is one place where the customer books a slot, the team sees the day’s work, and the customer learns when the car is ready. That is what we build.
