(a) Company A agrees to provide systems engineering and technical direction for the Navy on the powerplant for a group of submarines (i.e., turbines, drive shafts, propellers, etc.). Company A should not be allowed to supply any powerplant components. Company A can, however, supply components of the submarine unrelated to the powerplant (e.g., fire control, navigation, etc.). In this example, the system is the powerplant, not the submarine, and the ban on supplying components is limited to those for the system only.
