The functional baselines are further decomposed into their lower-tiered subsystems. The performance requirements of the system are then allocated down to the lower level functions.
This allocated baseline is used in the supportability analyses to project operations and sustainment requirements to be satisfied in the design of the support system. Support alternatives (contractor- supplied, organic 2 level, organic 3 level, etc.) are evaluated against the operations and sustainment requirements. Support alternatives deemed not viable (those not meeting all support requirements and constraints) are discarded. Those remaining become the basis for development of initial support plans and information products (e.g., technical publications, supply support, etc.).
Phase activities often include the development of product prototypes and the conduct of demonstrations and early operational assessments. These activities help to reduce risk at the Milestone II decision. Cost drivers and life cycle cost estimates are kept current with the design to reflect a more detailed understanding of the total system design characteristics. Engineering and manufacturing development phase Phase II of the acquisition process is used to complete a stable design for a total system which meets the performance requirements and is producible, supportable, and affordable.
Total system capabilities are demonstrated through testing to validate design assumptions, and deployment planning is initiated. Low rate initial production is begun during this phase to provide the minimum quantities required to support operational testing and other design validation activities and to establish an initial production base for the total system. The allocated baseline of a total system is transitioned into a full product baseline during this phase. In other words, functional or allocated designs are updated to physical or product baselines representing the actual product hardware. Support system designs are updated as well to keep current with the latest design.
The updated support information provides input to tradeoff and other program decisions that may be required. The updated information is also used to update or prepare logistic data products like spares lists, training packages, and technical publications required to implement the support system design. Production, fielding/deployment, and operational support phase Phase III includes all design activities needed to: 4-11
