TECHNOLOGY FOR TODAY AND TOMORROW A Typical Application Example of Concurrent Engineering In Chrysler Corporation
Annual Sales of Automotive Industry Chrysler Sales in 1998 65 Billion Ford 125 Billion General Motor 200 Billion We all use concurrent engineering methodology
Chrysler Manufacturing Strategy • We only make engine, transmission and body. • We buy more than 70% components from outside vendors. • We separate our design teams as: Large car, Small Car, Mini Van, Truck and Jeep, not like traditional, one department deals with all the cars. • We bought 30 billion parts from outside in 1997, and we still make 3 billion dollars profit
CE Characters General Manager for Small Car Design Body Engineering Supply Purchase Finance Manuf. Supplier: Part of family and extended platform. Sit-in but not Chrysler employee Co-Location: all team sit in one floor, communicate instantly. Tech Club: will solve the duplicate/redundant problems, there about 70 tech clubs Information flow among the platform, cross-grid.
