Supply Chain Chart: In this supply chain, raw materials including steel sheets, aluminum sheets, plastic pellets, electronic components, and tires are sourced through the purchasing department. The raw materials are then sent to component manufacturing facilities where engine parts, transmission parts, brake parts, suspension parts, and electronics components are made. These components are then sent to sub-assembly manufacturing facilities where they are combined to create larger sub-assemblies, including engine assembly, transmission assembly, chassis assembly, and interior assembly. Finally, the sub-assemblies are sent to the car assembly plant where the final car is assembled. The car assembly process involves body-in-white assembly, paint shop, and final assembly before the finished car is produced.
