(b) Matrices described The matrices described in this subsection are the following: (1) Engineering manufacturing and development goals A matrix that identifies, in six month increments, key milestones, development and testing events, and specific performance goals for the engineering manufacturing and development phase (referred to in this section as the EMD phase ) of the programs described in subsection (a), and which shall be subdivided, at a minimum, according to the following: (A) Technology readiness levels of major components and subsystems and key demonstration and testing events. (B) Design maturity. (C) Software maturity. (D) Subsystem and system-level integration maturity. (E) Manufacturing readiness levels for critical manufacturing operations and key demonstration and testing events. (F) Manufacturing operations. (G) System verification, validation, and key flight test events. (H) Reliability. (I) Availability for flight operations. (J) Maintainability. (2) Cost A matrix expressing, in six month increments, the total cost for the Secretary’s service cost position for the EMD phase and low initial rate of production lots of the programs described in subsection (a) and a matrix expressing the total cost for the prime contractor’s estimate for such EMD phase and production lots, both of which shall be phased over the entire EMD period and subdivided according to the costs of the following: (A) Air vehicle. (B) Propulsion. (C) Mission systems. (D) Vehicle subsystems. (E) Air vehicle software. (F) Systems engineering. (G) Program management. (H) System test and evaluation.
