The establishment of a dedicated program office with the requisite engineering and support skills will provide the basis for assuring a quality product. The overlaying of this structure with senior management support and review on
work will enhance the regular basis will

Design and Manufacturing Controls
The design of the system and each subsystem will be rigorously reviewed within the project team using
using the specification as the vehicle. Specification reviews will be held periodically to ensure design compliance. Careful attention will be paid to the use of proven designs and to the specification of interfaces. Quality assurance requirements consistent with commercial practices for all hardware and software developed by the Contractor or Subcontractors will adhere to the specifications. This will encompass not only design, but manufacturing and parts
