Vehicle manufacturers are simplifying their manufacturing processes by reducing the number of vehicle platforms they use-so-called platform sharing. Vehicle platform sharing is a product development method that uses a shared set of design, engineering, and production factors, as well as major components over a number of vehicles and brands. For example, the Toyota Camry and the Lexus ES share the same platform. Do you think this is a good idea for vehicle manufacturers? What are the advantages and disadvantages of platform sharing? Do you think platform sharing played any part in Toyota's recall crisis?
