For those system elements for which organic support is required: Identify hardware candidates and support functions. Conduct repair analysis. Perform functional analysis and task analysis on repairable items for selected support system design. The available design data and the operations and support concepts should be analyzed to identify the hardware design repair candidates and the basic functions that should be supported (FA/A segment of the systems engineering process).
Analysis should be performed to establish a repair- versus-discard and a level-of-repair policy for each repairable item under each of the support concepts. This repair level analysis should be used to recommend the optimum repair policy and level of repair for the item based upon system availability life cycle costs (Synthesis and SA&C parts of the systems engineering process). Based upon the results a support system design can be selected. Repairable items should be functionally analyzed under the selected support system design to identify specific corrective, preventive, and other operations and support tasks (FA/A segment of the systems engineering process).
Tasks should be analyzed to identify their annual frequency, manpower and personnel requirements, elapsed times, task procedures, spare and repair parts, test equipment—in short, all logistics resources needed to perform the task (Synthesis part of the systems engineering process). Factors that relate system characteristics to support task requirements like annual frequency and hardware reliability should be easily traceable to ensure that the impact of any changes can be recognized and addressed (SA&C portion of the systems engineering process).
Support factors such as manpower requirements and sparing rates should be related to hardware oriented maintenance planning factors like the annual operating requirements of the system and the individual task frequencies. This action maintains the linkage between requirement, design, and support. The detailed task information should be used as the source of information for preparing required logistics data products. A notional supportability analyses process flow for a Commercial/NDI acquisition is shown in Figure 5-1. 5-9
