PROCESS STRATEGY AT WHEELED COACH
Wheeled Coach, based in Winter Park, Florida, is the world’s largest manufacturer of ambulance.
Working four 10 hour days each week, 350 employees make only custom-made ambulances. Virtually
every vehicle is unique. Wheeled Coach accommodates the marketplace by providing a wide variety
of options and an engineering staff accustomed to innovation and custom design. Continuing growth,
which now requires that more than 20 ambulances roll off the assembly line each week, makes process
design a continuing challenge. Wheeled Coach’s response has been to build a focused factory.
Wheeled Coach established work cells for every major module feeding an assembly line, including
aluminum bodies, electrical wiring harnesses, interior cabinets, windows, painting, and upholstery.
Labor standards drive the schedule so that every work cell feed the assembly line on schedule, just-in-
time for installations. The chassis, usually that of a Ford truck, moves to a station at which the
aluminum body is mounted. Then the vehicle is moved to painting. Following a custom paint job, it
moves to the assembly line, where it will spend 7 days. During each of these 7 workdays, each work
cell drivers its respective module to the appropriate position on the assembly line. During each of
these seven workdays, each work cell delivers its respective module to the appropriate position on the
assembly line. During the first day, electrical wiring is installed; on the second day, the unit moves
forward to the station at which cabinetry is delivered and installed, then to a window and lighting
station, on to upholstery, to fit and finish, to further customizing and finally to inspection and road
1. Why do you think major auto manufacturers do not build ambulances?
2. What is an alternative process strategy to the assembly line that Wheeled Coach currently uses?
3. Why is it more efficient for the work cells to prepare "modules" and deliver them to the assembly
line than it would be to produce the component (e.g., interior upholstery) on the line?
4. How does Wheeled Coach determine what tasks are to be performed at each workstation?
