PRODUCTION AND INTEGRATION
The MRAP production and integration process is best examined in terms of the value stream from subcomponents through the final integration effort and transportation to warfighters in Iraq and Afghanistan. This basic process, as shown in Figure 15, begins with the numerous suppliers to the five prime contractors manufacturing the vehicles. These suppliers produce the components and subassemblies such as engines, transmissions, axles, and seats. Within this supply base exists some of the bottlenecks associated with MRAP production, such as armor and, initially, tires. To demonstrate the complexity at this level, the JPO has identified 62 major Tier 2 vendors17 for 15 critical sub-assemblies (Hansen, 2008, June 4, slide 11).
