This next section of the report focuses on key processes within the value stream, starting with critical resource constraints at the supplier level and actions taken to mitigate these potential bottlenecks to production. It also provides an overview of the actual production process, with vignettes from two of the largest MRAP manufacturers, a major Tier 2 supplier, and the integration effort at SPAWAR. The interaction and quality assurance provided by DCMA is critical throughout this process and is also examined.
Some of the primary components and subassemblies supplied at the Tier 2 level include axles from three manufacturers, four different engines from three manufacturers, multiple transmissions from one manufacturer, and suspension components from nine manufacturers (Hansen, 2008, June 4, slide 11 and MRAP JPO, 2008, June 2). Of these items, as well as most other components, sufficient capacity existed within the defense and commercial industrial bases to meet the demands of the MRAP program. When added to existing demands from commercial businesses as well as other programs within

explosively formed penetrators (EFP) which became prevalent after the start of the MRAP program. It is installed in the Charleston area vice at the OEM (original equipment manufacturer) site due to its weight and bulk.
